This one is for the guys to answer.
I have posted the same thing in the "For Her" section for the ladies to answer/

Have you ever been in a situation where you had to (or got to wink ) share a bed with someone that was not intended to be a sexual encounter of any kind, but was just so horny that you couldn't help but touch yourself and try to discreetly, quietly and gently masturbate so you wouldn't shake the bed and get caught by the person laying next to you?

maybe just because you were horny and nothing to do with them?
Maybe you were turned on by them?
Maybe you have been one of your masturbation fantasies that you have thought of and masturbated to before already?

Or have you maybe been in the situation of sharing a bed with someone who masturbated next to you and they though you didn't know?

I have done this a few times, but one of my favorite experiences was a few years ago when a friend of mine asked me to go on a trip with her and we shared a room with only one bed.
We are good friends, so I was not going with the expectation of anything happening between us, but still, she is very hot and I have often masturbated to her in the past, so I can't deny that I was secretly hoping something would, but out of respect for the friendship, I would have to let her make that first move. Unfortunately, she never has. But spending a weekend on a beautiful island with a beautiful girl, hanging out in the club listening to a great rock band and drinking the whole time and knowing that at the end of each day you're going to be in bed, laying next to this gorgeous woman you have not only thought about while jacking off for so long, but also admired for many years, not just for her beauty and sexiness, but for the personality and the whole package, even if it wasn't going to be sexual, it was still unbelievable that I was getting to just be there with her laying next to me.
At one point, when she rolled over, facing away from me, I also rolled over the other way where my back was to her back and slid my hand in my pajama pants and into my panties and just quietly and slowly rubbed, squeezed and stroked my cock as easily and gently as I could so as not to shack the bed to where she would know what I was doing. I didn't want her freaking out or getting creeped out by me playing with myself right next to her. I didn't cum, but just softly rubbed and stroked until I fell asleep and woke up a few times with my hand still in my panties playing until I went back to sleep again.
I do have several other female friends who I openly masturbate with, but this girl and I have never crossed the line into anything sexual. I feel (or maybe just wishful thinking) that at some point it could be, but so far it hasn't gone there. Maybe next road trip?
I'm just if she knew what I was doing right next to her in bed those nights on vacation.
Also wonder sometimes if maybe she ever masturbates to me.

Kind of. I was on a camping trip once with me, another guy, and a couple. We were all in one giant tent, so we could spread out a bit.

I woke up really late in the night. In the dim light I could make out the sleeping bag of the woman moving around. I finally figured out she was masturbating, I saw her whole bag shake as she let out a very quiet moan. If I hadn't already been awake I wouldn't have heard it.

I waited a bit for her to go back to sleep, then pulled off one of my socks and jerked off into it. (Fortunately I had a clean pair to put on in the morning).

I have shared a bed, snuggled, etc. with many of my female friends since I was a teen. Usually I do not masturbate while in bed with them, unless they were already one of my masturbation buddies, but usually with the girls who are just friends and nothing more I just enjoy their company and cuddling up with them while sleeping or watching TV or whatever, but I have snuck in some stroking with a few of them.
I just wonder if any of them ever figured out what I was doing and just never said anything since my ex-wife used to always know when I was jacking off because she felt the bed shaking even when I thought I was being very careful and going slow so it wouldn't disturb her. (the ex-wife only complained about the bed shaking when she was trying to sleep for a short time but then got used to it after a few months and it didn't bother her anymore. She got used to it and said it actually relaxed her and she had a hard time sleeping if I wasn't "rocking her to sleep" by jacking off. lol
I have had girls masturbate while laying next to me, but they were girls that we did that anyway. So far, I don't know that any of my "Just friends" girls had ever masturbated next to me in bed.

I have on several occasions jerked off next to my sleeping wife usually after an argument as a form of revenge and tension release.

i have jerked off in bed next to my wife at times....sometimes cumming on her ass when she is sleeping....

Not since I was 13. I stayed overnight at a friends house and we shared his bed at night. I woke up to the sound of him jacking off next to me. He was really into it and pumping hard, grunting as he jerked his dick. I couldn't resist jacking off too. Of course by then it was no longer "secret." We both jacked off twice that night.

Ive done it many times ...sneaky masturbation is hot. I also watched my nephew do it while he thought i was asleep. Growing up i probably did it at ever sleepover after my friends went to sleep.

Three occasions:

A sleepover when I was about 12. Woke up on my side to my friend rustling behind me. I couldn't resist looking over my shoulder and sure enough, he had pulled the sheet up and tucked it behind his head, making a tented space for himself to go at it.

I know now he most likely wanted me to join in. Unfortunately I was naive and didn't know people did that. I had discovered masturbation all on my own, not having any brothers or male cousins, and had never been in this situation. I thought he'd be mortified if he was caught. So I went back to sleep, empathy for his embarrassment overriding any horniness. I often lament the missed session, and possible future sessions we might have had together.

2:
I was about 17 and visiting my sister in college. She shared a house with two other students, and I slept on her bedroom floor. Something woke me, and I turned to see her really going at it under the covers, arching her back way up off the bed.

3:
Sharing a hotel room with a M-F couple and their male friend who I had met several times before and now shared a bed with. I was really horny on the trip and made a point to secretly take a washcloth to bed with me. I waited until his deep breathing indicated he was asleep and did my best to do my business quietly and without bed vibration. If he knew he never let on. I wasn't really after anything happening with him, I just needed to nut.

A friend of mine said I could crash at his place,(years ago).I could sleep in his chair-it was not far from his bed.I wasn't thinking anything sexual with him at all.
I woke up that night hearing him moaning in the dark.This is the first time a man had openly masturbated in front of me.I wasn't offended at all.
I thought if he was so horny would he be offended if I went over and starting playing with his cock and balls?Should I masturbate openly for him?
The next morning I was Super Horny and masturbated in the shower and came Nicely to the Memories. I thought it was Cool that he felt comfortable enough to Masturbate that night in my presence.Openly Masturbating in the presence of others is Liberating and exciting for All present to express their true selves and their Sexuality don't you think?(either gender).
I thought it was Great that he shared his masturbation with me.
Later on he admitted to me that he could go either way.I didn't want him to think I was sexually interested.I didn't act offended when he mentioned his bisexual desires.I didn't pursue anything sexual with him.He was my friend though.

About a year after college graduation I had an apartment in the same town where I had attended school, although many of my friends had moved home. A hot female friend called and asked to stay with me when she came in to meet with one of her professors, and of course I agreed. Although I had wanted her for years, there was nothing sexual to our relationship. We slept in the same bed together, but nothing happened because I didn't think I had a chance and was being respectful.

My alarm went off the next morning and I am running late.. I had my dream job as a DJ, but it required me to get up very early. At that point I had been late twice and missed one entire shift, so I was on my last chance. My friend had agreed to come to work with me. She threw off the covers and climbs out of bed. She is just wearing a t-shirt and leopard panties. I had to idea where here PJ pants had gone.

We hurry, get dressed and head to my work, where I was solo because it was the weekend. Few hours later she says she needs to change and looks me straight in the eye as she starts to strip. When she gets down to nothing but her bra and panties, she peels the panties off and tosses them too me. They are soaked.

'You shouldn't be such a heavy sleeper. I played with myself for over and hour hoping you would wake up.'

She told me if I did it in the room while she was getting dressed I could borrow her panties to jerk off. So I did, all over the control board while she watched. She kissed me goodbye and I didn't see her for ten years. By then we were both married with kids.

I used to have to because i had a difficult relationship

Oh ya. When I had Cinemax I'd watch the soft porn on there and slowly jack off and cum while my wife slept.

Hooked up with a really hot girl in a bar many years ago. Went back to her place, got in bed in our underwear, made out for awhile, snuggled and she fell asleep. Once she was sound asleep I pushed my shorts down and layed
there looking at her while I jacked off, I squirted my cum on her leg. Got up the next day said goodby, I wonder if she realized what I did.

Not in the same bed but in bunk beds.

Not same bed, but bunks on a ship, where I could look over and see he was humping bed while looking at porn mag. Listened to my friend lube his cock and jack it while I spent the night. I was in bed right next to him. Wish I would of joined in.

Had another friend where we would sleep in same twin bed. Never did anything but wish I would of jacked. We spent a lot of time looking at porn mags and watching tv shows with barely clothed women and some porn vids
