Sex before marriage question?

So i'm a 17 years old virgin. I talked to a friend about if she ever wanted to have sex just to see what it was like and she has already had it before. I'm just a teen wanting to know what sex is like and I don't want it to be all about lust fullness as more as something I want to experience. I'm a Christian and i understand the bible states that sex is something to be done between a married man and woman. Thank you.
