I am a woman who has tried the "grapefruit" technique on a man

I dont know how many of you guys have heard of the grapefruit technique but there are good descriptions of it online. Basically, you take a grapefruit, warm it up, cut off both ends, and then make a hole through the center of the flesh of the fruit, just wide enough of a penis. If a man puts his penis in that hole, if apparently feels exactly like a vagina. The technique is then to put his penis through the whole and jerk it up and down while simultaneously sucking him. To the guy, it feels like he is in a vagina AND getting sucked at the same time. Guys always love it, and are always surprised how much they love it
