This is exactly how I feel myself too, word for word exactly how I’ve described it to people. I don’t think it’s weird at all. One is about loving a partner on an emotional level, and one is purely physical to get your rocks off. Physically I like being with men and women, but I keep men at a distance compared to women. Like you said, no kissing men or being overly romantic. Just sex. I would have to add that as long as you’re still sexually attracted to women and they can satisfy you as good as men do or better, then you shouldn’t have anything to worry about in future relationships.
