We've been dating for a few months now... I am 23 he is 21 years old. We have been intimate before and we have kissed ones before. He is an amazing kisser, but after that one time he stopped kissing me. He claims that he doesn't like it but I feel like there is more to it. He also moves away when I try to kiss him.
I am OCD about my hygiene, so it can't be my breath and I know I'm not a bad kisser.

We recently talked about what we have done as far as oral sex etc. and I feel like that is the reason why he doesn't want to kiss me. I've only given oral to one person... Sooo... I dono... I even asked him if that's the reason and he says "No I just don't like kissing"

Our relationship is great but I'm considering to break up with him because I don't feel like we're "together" due the lack of kissing.

It could be that he feels detached when he is intimate with you. Maybe he doesn't see it as "making love", but just sex. You don't want to break up if you have a great relationship as you said, but you do need to get to the bottom of this "hang up". Probably would be a good idea to see a counselor together. But again, I base this solely on your statement that you have a great relationship. But if I'm being honest, I would feel exactly the way you do if my partner refused to kiss me. But I wouldn't be so sure about the "breath" part. It would definitely give me a complex.. But that's just me.

Don't break up with him his maybe just waiting for a specific time or he just thinks you feel uncomfortable

I hope that in the two years since this question was asked the op and her boyfriend worked things out.

To others reading this question with the same issue: Talk to your partner and ask him her to be completely open and honest about why they aren't wanting to kiss. Listen without getting defensive to what they say. It may be something you can 'fix'. It may be something about their own health causing them to pull back. It may be a factor unrelated to the act of kissing. It may be too soon in the relationship for them. But you won't know unless you are both open and willing to discuss it.

If communication and compromise can't be found in a reasonable amount of time, then you have to decide if the relationship is as 'great' as you want it to be.
