We've been together for 2 months, and our relationship is sexual but there is little or no kissing why?

I think because its all lust, and NO love. At least not from him. How old are you both.

He may have a problem with that kind of intimacy. Do you know if he was like this with previous girls? Is he affectionate with you in other ways? If, as it clearly does, matters to you then you do need to draw attention to it as clearly it is intimacy that matters to you and most people. In addition you could perhaps dig around on the net and see how typical it is.

All sex and no kissing seems pretty impersonal to me. Do you two ever talk? Ask him. Tell him what you want. How old are the two of you?
