I had a thing with this guy Billy for about a year, and I lost my virginity to him. we were never technically a thing but I fell for him. the day after I lost my virginity to him he hooked up with another girl. a couple of months later I started dating another guy and we were together for about a year then we broke up... Billy and I recently started talking again, and he seems like a changed man (much more mature), but I'm not sure if we should talk talk again (have sex) please help!
