72 Virgins

In one sect of Islam, if a suicide bomber blows themselves up along with any infidels, the person who did the bomber gets to pass to heaven where they spend eternity with 72 virgins. Apparently this is some kind of a reward for killing innocent people. I don't see how spending eternity with 72 virgins is a reward. Having been a virgin myself and having been with a virgin or two, the first-time experience wasn't all that rewarding. Basically my partner just laid their with her legs open. They wasn't much excitement to it. My partner was inexperienced and didn't know what to do. It seems to me, a much better reward would be 72 experienced woman, who could show the man a much better time. Being with an experienced woman who knows how to use her body and use a man's body is a much better reward. Perhaps the man that came up with this idea of heaven had never been with a virgin and just assumed it would be heavenly to deflower virgins.
The other thing I don't quite understand is: what happens after the bomber has deflowered his 72 virgins? I mean after 72 years, or 72 months, or 72 days, or 72 hours, or however long it takes to deflower 72 virgins, what happens next? Do the virgins stay deflowered for eternity or do they come back to you the next day with their maidenheads restored? If they come back everyday with their maidenheads intact, what does that say about the bombers manhood? “What's the matter, can't you deflower a virgin and get her to stay deflowered?” “What kind of a man are you?”
Also, where do the 72 virgins come from? Is their a bottomless pit of virgins that is continually drawn from? And, how rewarding is it for the virgins to lose their virginity, which I have been told is painful for the woman, and then have it restored, only to painfully lose it again? Doesn't seem like paradise for the woman? And what about female suicide bombers? Do they get 72 male virgins? And why 72? Why not one virgin per day for all eternity? I need someone to answer these questions for me to help me understand what this paradise is all about. In suicide bomber training school, are these questions answered? Someone help me to understand.
The claim that paradise has 72 virgins waiting for suicide bombers is absurd. This just another example of the perversion that is religion. Religion is dangerous but extreme religious beliefs like this have deadly consequences. The sooner the absurdities of belief are pointed out; the sooner those beliefs can be done away with.
