I think you'll find that everyone here is about free choice, as long as it respects the rights of everyone involved. I think it's great you have found something you enjoy. If you are happy with your choice, then it's really not anyone else's place to judge. From a perspective of relationships, I think it's just necessary to find someone who shares and enjoys your interests and values.
As my life has progressed, I have come to reflect more and more on how important compatibility is in relationships. I'm a counselor, and I see a lot of couples whose only problem is that they have different preferences. For example, if one person has a very high sex drive and one has a very low sex drive, one is going to be frustrated and the other is going to feel put upon. Obviously, your sexuality is very important to you so it's going to be crucial for your mental health to find someone who is compatible in that area. In the meantime, it sounds like you're expanding his horizons a little:) And there is absolutely nothing wrong with a little horizon expansion:p I enjoy reading your posts. I hope you stay on the forums.
