I (25m) have been experimenting with more things with my girlfriend, and we started with rimjobs.
And now she's interested in pegging and prostate stimulation. My problem is that I've tried it before and barely felt anything.
Exploring it myself and with my ex-partner, the pleasure I felt was more mental. I've read stories from guys who say they feel shocks of pleasure when their prostate is stimulated, but I don't feel it, and I wonder why.
