First off, I am no virgin and had my fair share of relationships and afairs.
As many others have mentioned, if you havent had sex, it might seem something mythical, but rest assured, it isnt. If there is no feelings involved, it might well be pleasant, but it really doesn't change anything in your life.
And for all the youngsters out there - I really didn't have much sexual activity up to my thirties and I dont think I was very attractive to girls back then. This changed a lot and I am approached by girls 10 or more years younger than me even - so things can change!
I wish I could have kept my special one, though, without her, all the sex and all the chatter just seem meaningless in the long run.
Sex for pleasure isnt evil between two consenting adult. It only begins being a problem, if one person gets attached then and the other does not. More a question of balance than of good vs evil. I agree that the ultimate thing is a loving relationship with good sex, though. Been there, messed it up.
Take care guys
