Wanting sex ( phone sex) all the time

I'm talking to a guy who doesn't live near me but visits during the summer. He took my virginity freshmen year and we have been doing things together since then. When he isn't here he gets mad that I don't want to get on FaceTime and us basically masturbate to each other. What he doesn't reallize it that it's tiring to me and it's not like I have him over here physically returning the favor. It also hurts for me to masturbate vaginally instead of just rubbing my clit for me and it its painful and I have told him this but it's almost like he doesn't care. I moan and all that stuff squirt all things I don't care anything about all for him. I am not really a sex person but every now and then I am horny and would like to do things. However he wants to do something almost every day and I don't. He has been very disrespectful about it yelled at me and all sorts of stuff and when he is here if he doesn't get what he wants and I say no he acts all kind like I'm not gonna force you but then takes it out on me later. I am too the point where us having these stupid arguments is too much and I'm going to have to stop talking to him because we already have other issues going on and I can't keep living like this anymore. Any advice or someone who has had this problem that knows how to deal with it.
