Is it possible to get over this deep set aversion to kissing?

I experienced a gay sauna for the first time a couple of days ago. I was anxious for a few minutes, until I got a feel for the place and let my towel expose me a bit. I had two encounters and both were fantastic. (If you're following my previous post, I'm in the very beginning stages still...) However, both times, my partner expected kissing, naturally. But I have always had an aversion to tongues and kissing in general. This confirmed it. Interlocking tongues with another human is not my thing. It feels disgusting and I was cringing a bit during that part. (I say this but I was the bottom...) I felt strange saying that I don't kiss, but maybe that's acceptable just like any other boundary. I am wondering, though, if it is possible to get over it.
