I've been seeing this gentleman for two months now. We went on dates a couple times. We probably went on maybe about 7 to 8 dates. It was going good for a while. But we stopped dating and just went on casual sex. The reasons on our both ends were we were both busy with work. Which is true, we were busy. Then, I started realizing he would just call me on his days off to have sex. The sex is too good to let go, but I'm weary. I like this guy. But I'm worried if I should say anything to him about our situation. I don't want to lose him as a sex partner but I don't want to just have casual sex from time to time either. I would like to start some kind of relationship with him but I don't know what I should do.
