Feeling Guilty About Sex?

Why do I feel so guilty about sex? And how can I stop feeling guilty? I am a Christian and my parents have always been EXTREMELY religious but they’re finally getting out of the religious, lawful, part and more into the faith if you will? Anyways I’m 17 and i understand that it’s a special but also a NATURAL thing.. Im a virgin which makes it all the weirder. But I think of it and I have been more recently, and then I just feel super guilty and gross about it...

How can I stop feeling this way and just own up to it?
