The first thing you have to do is separate your sexual desire from your desire to be kissed and hugged. If you don’t want to ruin this relationship, have sex with him once a week and masturbate the other six days or nights. Hopefully if you remove the pressure from him, which makes him think that if he hugs or kisses you it’s going to lead to sex, then he’ll be able to satisfy those other needs for you. Of course there may be other things going on in your relationships that has been causing these problems. I don’t know enough to add them into the equation. But if the situation is entirely as you describe it, I think you can keep this relationship together by separating the sexual aspects from the romantic ones.
