Should I be having sex?

I am a 17 year old male, and most of my friends are sexually active, often bragging about it as most guys do. I feel somewhat inferior to them when they speak of such things; I am actually not that close with any members of the opposite sex at all. This feeling of inferiority has prompted in me sexual thoughts and the desire to have sex as well. After a while it's something I've concluded isn't for me; I just don't think it's respectful to take a girl's virginity before marriage knowing very well that you probably won't be together forever or even the rest of the year, or to simply use a girl for sex when you don't even have feelings for her. I'm also somewhat religious, so I'm fairly sure God frowns upon such a thing and I have no desire to go to hell just to get some sex (I'd appreciate no comments with anti religion content). So there's my dilemma; on one hand I have my desire to compare to my friends, and on the other my moral code that's holding me back, any thoughts?
