Relationship troubles: he doesn't kiss me.

Hi!

So long story short, my boyfriend isn't very affectionate. Nowadays I have to bug him to have sex, and the big thing is that he doesn't kiss me. I have to ask for kisses, and when he does, it's just a quick peck. He doesn't passionately kiss me, he doesn't make out with me. We'll have been together for 2 years come this September. He said to me today "making out is gross. I'm not 16, I don't like making out." But he didn't feel that way when we were in the earlier stages of our relationship. He's become distant, even in conversation he isn't as engaged as he used to be. When we're together we kind of just do our own things.

It honestly really hurts my feelings. This whole distance thing--not kissing me as well--makes me feel unwanted. Like why wouldn't you want to kiss your significant other? Am I a terrible kisser? Am I not attractive? These are the things I start to question, along with if he even still loves me. But when I bring it up, he dismisses it/doesn't really talk about it and says he doesn't know what I'm talking about and that he does love me. But you can tell when someone kisses interest. Like he says one thing but his actions and overall body language say something different. What do you guys think?

Thanks xx
