I was taught this trick years ago. I would visit the oriental spas from time to time. Yes, the "Happy Ending" ones. You always start with a table shower, where they clean you up very well, a couple of minutes in a sauna to get your body warmed up, then are shown back to the room. First visit, you may not have the Happy ending, but if you visit again, you will find out. They give you a hand job with baby oil, and if you take a bit of time to cum, (sometimes you will) the masseuse will slide a finger ( oiled of course) in and rub your prostate. You will pretty much cum immediately.
I taught my later partners the trick, and if they care about you, they will gladly perform it for you. Just remember, you can use the trick on them too! No women do not have prostate glands, but when you are licking her clit to orgasmic pleasure, I have found that it is very welcome, and can give them a more intense experience, if you lightly slide your left index finger into their wrinkled sensitive bottom, as she starts her orgasm!
Have fun!!
