It's me - again

Today in college was weird. Two friends of mine came to talk to me - not at the same time, let's be clear - and both conversations ended up talking about sex. I know, sex is a taboo in a lot of places, even now, in the 21st century. But, lets face it: it's a natural thing.
The first friend that came and talked with me (I won't tell his name. It isn't fair with him) asked if I was virgin. I answered that yes, I'm virgin. Please, this isn't a time to judge. He asked me why and I gave him a lame excuse (yes, I admit it was lame). He told me that the excuse was lame and everything. So we tried to move on the conversation to another subject cause I was getting kinda embarrassed (it IS embaracing to talk to a male friend about sex when you're a girl). Several hours later, another friend of mine (that I'll also not say her name, in respect) was talking to me and the subject also ended up in sex. She made the same question my other friend made and I answered the very same thing. But she quite understood my point when I told her I didn't think it would happen so soon.
What if I had lied to them and said that no, I ain't virgin anymore, but not with a huge romantic thing, but through rape. I guess that their reaction would be of total shock (and in the second situation would be quite lethal once my friend was driving). I know it happens to a lot of girls (and boys too) so I think that it shuldn't be such a taboo, anyway.
What I wanna say with this is: why is there that huge pressure for people (girls AND boys) having sex when they get in college? I mean, nothing against people who do it, but why it has to be an "universal experience"? I get the whole new-life-new-expiriences stuff, but c'mon!
I'm not gonna preach that whole sex-after-marriage kind of stuff. It just ain't me. I think it's bullcrap, even for nowadays. Especially for nowadays. I just wanna make people think about the romantic side of all this. Ok, it might have sounded a little weird, once sex, most times, sounds nasty. But the point is: do it just for doing it? Is it really that necessary? I mean, would you do just to be able to tell your friends "hey, I just got laid"?
I guess that's all. I think I just wanted to raise those questions, so they could be discussed.
See you guys later

PS: No, I haven't lied to my friends. Nor in this post. Yes, I'm a virgin.
PPS: Let's make it clear. I do have a boyfriend.
PPPS: I think I must repeat this: I'm not against sex-after-marriage thing. I just don't think it works for everyone.
