The prostate is very similar to the G-spot, says Glickman, and the reason why men like prostate play is because, every time it's touched, it feels like the beginning of an orgasm. But instead of that feeling only lasting for a second, it lasts as long as it's being touched.
"The prostate is around three to four inches inside the rectum and about an inch in diameter," Glickman explains. "It's easier for a partner to find after a little flirting or foreplay because when the prostate is aroused it starts producing fluid that makes it fill up like a water balloon." Transgender women also have prostates, Glickman says, but if you're using hormones to transition, it may shrink and become less sensitive.
When you find it, Glickman recommends stimulating it the same way you would the G-spot. So take G-spot techniques such as the come-hither motion, small circles, windshield wipers, and tapping. He says to make sure you "stroke don’t poke," use your finger-pad not your fingernail, and take it slow and steady, starting with lighter pressure.
