Of course, why wouldn't it be ok? I don't even think it's necessary to say you're "uncomfortable". If they were talking about golf or bowling and you have no interest in those topics, you would excuse yourself and go birdwatching in the woods. If you say you're "uncomfortable", people tend to think there is something they should do or not do to keep you from feeling that way in order to convince you to stay, and that is obviously not what this is about.
You could say "I'm going for a walk and I'll let you "married couples" have some quality time together".
I really don't think it's that big of an issue in and of itself.
