How do i increase the pleasure of the orgasm as a male?

Delay it.

take your time, don't just rush to the finish
the longer it takes the better it feels

-Edging (almost orgasm, calm down a little, almost orgasm again, repeat for as long as you feel like)
-Wait at least 48 hours between each orgasm
-stick penis in woman, but be careful, do not make babby

Be uncut

I'd say figure out his kinks. Yeah I'll cum from whatever but a girl who will indulge in my fetishes will make me harder for longer and have a better orgasm. Maybe you could try be more submissive or more dominating and see what he responds to more. The delay idea also works.

Is prostate orgasm real? How do i do it without external objects?
