I've masturbated in many places among them my room, the bathroom, on my mother's bidet, in cars, the woods, uder water while skinny dipping, at school in the showers, on beaches, even in a cemetary. The last place was really convenient because it was wooded and easy to hide in.

lying down in bracken in the country
on a deserted beach (at least twice)
in most rooms of my parents house (once in the lounge when watching "Eye of the Cat" on TV)

in public and pub toilets

I'm probably still missing some. Funniest thing is that no matter how many places I've been, I'm still missing an important one on my list: with someone else.

I got to the beach really early, one morning, when I was in my late 20s. I was on the boardwalk under a pavilion. I had just finished cumming when a middle-aged couple came up the ramp. I thought I could see anyone coming from a long way off, but I was wrong! I got my bathing suit up just in time--I think. Anyway, they didn't act like they saw anything.

I've also masturbated in the woods on a hiking trail (on days when the park was almost deserted).

I lived on a farm so i have jacked off in a lot of places.
