Experimented with same sex during college years, but fell in love with my wife and been monogamous since. She's actually the only girl I've ever had sex with, so by default the best! She knows how to push my buttons / drive me crazy so no desire to experiment any further :) My fantasies are still often bi-sexual, I'm not picky when it comes to porn.
What you describe is autosexuality. Very common and cross-dressing is part of that. Or overlaps.
