Straight guy here, with my current partner she was feeling a little friskier than normal and after using a vibrator on her she asked if it feels good on guys. Well she started working from my dick down the shaft and to my taint. It felt a lot better than I imagined and asked if it felt good farther back, I said I’m willing to try and she ended up massaging my prostate with it and holy hell that’s an unimaginably good orgasm. Finally understood why gay guys like to bottom. She’s not big into anal and it was a little too messy for our taste to revisit, but I might try again at some point in the future by myself in the shower or something.
