[M]y first time finishing in my girl[F]riend back in college

First a little backstory – some years ago in college I dated a fantastic girl for a few years who we’ll call Kate. When we started dating I was a shy virgin who hadn’t ever gone further than making out and thought that I was saving myself for marriage. She was much more experienced than me and made it very clear that she wanted to have sex but wasn’t going to pressure me into doing anything I didn’t want. Well as it turns out I’ll say yes to anything if a girl takes her shirt off and she took my virginity a couple weeks later. Soon she had practically moved out of her dorm and into my off campus apartment.
