I’m heteroromantic and pansexual, if that’s what you mean. I’m down to have sex and attracted sexually to people, regardless of their gender, but I don’t want to date women. I don’t get butterflies about women (maybe once or twice in my life), and I just don’t have the romantic pull towards them that I do men.
My husband is actually about the same. He’s never dated or really wanted to date men, but he does enjoy having sex with them. He tends to just identify as bi (as do I, if I’m not being really specific), but also rarely volunteers any information about it, which most people assume means straight, especially given he has a wife.
