I have to wonder: “Why are you just now asking about this?” Two years? And it only now has occurred to you to wonder?
Look, I love kissing. I like ‘actual sex’ a lot, too, so don’t get me wrong. I can neck and canoodle for hours and enjoy every minute of it. The sometimes-teasing course that it can take – and for so long, when the partners both enjoy it for itself and not as a prelude to anything else! – and the way that it can be used for hours (or days, even weeks) to build to terrific sex – it’s great.
But it’s not the kind of thing that I would ask about—two years into the relationship. If my partner in a new relationship doesn’t like kissing, then the relationship has a huge strike against it. (I had a relationship of several years with a woman who was physically and emotionally incapable of having intercourse, and I was fine with the intimacy that we had, even so. She was a great kisser, and liked it as much as I did.) I might not come right out and ask whether she didn’t like kissing in general, or my kissing in particular, but one way or another I would resolve that – or accept that “she doesn’t like that”, and make plans accordingly (mostly, to look for a new girlfriend).
But this is the kind of thing that you find out about early, and talk about at the time, or adjust your expectations and work on the other aspects of the relationship that make it worthwhile to you. You don’t wait, and then two years into the relationship wonder out loud, “Hey, y’know, I’ve been wondering …”
But better late than never.
Don’t drop hints to him about how much you like kissing. Don’t sigh at romantic comedies when the hero gives the heroine a three-minute liplock. Don’t cast wistful glances at young lovers lying face-to-face in the grass in public parks this summer, oblivious to the world around them, and expect your boyfriend to pick up on your unstated intention.
Ask him. Or dump him. Don’t ask us. But do ask a close girlfriend to check your breath and give you honest feedback. Fix that if it’s a problem. Talk to the boy!
If he needs lessons, I don’t mind demonstrating with you while he watches.
