I don't have a handheld shower head anymore , but I loved the pulsing of the water underneath the head of my cock.

I have a traditional tub & now I kneel with my cock under the faucet & change the water temperature as it flows over my cock...good for a hands free cum !

Some of the best orgasms!! I also lay down in the tub with legs spread and let the show beat on my cock. Sometimes just before I cum I'll turn the show to cold with my foot.
Also the pool jet works great too!!

Does blasting your cock with cold water really do anything?? I've always just used warm water when jacking in the shower. Or do you mean make the water cooler, but not cold?

If you can get a single stream of water adjusted just right...It feels wonderful on your asshole. I've done it laying on my back with my legs up over my head(shot in my mouth a couple of times),but now I can't do that without somebody untangling me,& do it on my hands & knees with my ass in the air.
