I am 19 and my girlfriend and I have been together for a little over 3 years. She was my first official partner (besides a little something that happened with a guy before I came out.) I love being in a committed relationship and it is so much better for me to be in one. Sex to me is about the intimacy, companionship, trust, and love that you get from another person that you are committed to. Sex with her has been amazing. We've done nearly every goddamn thing in the book. There is nothing I wouldn't do for her. I couldn't see myself giving my body away for something that is not even a commitment. Mind you that before me and her got together, I did not feel this way at all. I said "who cares, it's just sex." But the love my girlfriend and I share has made me realize that sex is so much more.
