I'm still a virgin.
I wouldn't want to defile my body through fornication.
I believe that sex is sacred and holy and should be reserved for marriage only. I think I could safely assume that the majority who are in love and married wish that they would have never of had sex with anyone else except their wife or husband.
Chasity is a great thing. I do not see how people could just give up their bodies to others who have no sacred union between them. Many people could be in love and wish to express their love through sex, but they have yet to fully commit themselves to one another through holy matrimony.
