Naughty time

I met a guy online through chatroulette. At that that I was thinking that he looked cute so we exchanged some contacts. We chatted for a while. He and I are not much of a talker so we don't talk a lot until last night he suddenly felt clingy, saying things like "I want to feel wanted, you want to see me". By this I already know he wanted to have phone sex. So I told him I wanted to see him. And we did it. I saw him masturbate and I was giving him a show too. But I had this weird issue about intimacy, I'm scared that I can't talk to him the same way I used to, or he wanted it again. Because for me I don't do it often. I want to cut contact with him but at the same time I still want to see his smile. Oh and he has big dick.
