I had been dating this guy for about a year and a half when he started to get really controlling. He would insist that I call him at least a couple of times when I was out with my friends, and he told me that he physically hurt when I went out without him. I finally got sick of him one day when I was out with my guy friends, so I started to flirt with this guy, Gary. Later, we all went to a friend's house, and somehow Gary and I were left alone in my friend's bedroom. Things got hot, and we ended up having sex. It was the first time for both of us.
