i dont understand why you want to keep you virginity.
The basic rules of survival (AKA natural selection) is:
Get Shelter
Get food/drink (to live)
Repopulate your species
In most animal species, they begin reproducing ASAP. Guinea Pigs (i have then) 2 weeks after birth they begin repopulating.
Now then, off from that. If your believing you'll go to 'hell' for it, you'll join many many millions, so dont worry, i'm atheist, and i dont believe in a heaven or hell. Is there a possibility? Yes, but I refuse to spend my mortal time dwelling over the fact that i will go to pits of fire since if you repent to 'god' you'll be saved.
