i've heard that having the prostate massaged during oral sex or right before an orgasm is an unbelievable experience. i have been considering asking my girlfriend to try this but i wanted to know if all the hype is really true. if so, is there a method to follow to get the most out of the experience.

Yes it's true.

The best method is probably for her to use a flexible silicon toy and massage the area. You'll know when she hits the spot.

Don't forget the lube.
