I'm only speaking for people who identify as sexual in some way, as that is my experience; though I'd love to hear input from ace-identified members). I don't know if my experience is common, but I feel like I can experience physical attraction to people for whom I'll never have romantic feelings, but never the other way around (for me, those are platonic). So like even when I've had an okay time physically I didn't always feel the same way romantically in past relationships. Talking with a bunch of other people who identify strongly as gay or hetero but who have had experiences outside of the gender they prefer, it seems to be a more common thing than I realized. Sure, many/most lesbians don't feel any attraction to men, and many gay men don't ever wish to sleep with a woman, but others might enjoy physical intimacy with a member of a gender other than the one they primarily are interested in romantically, while only pursuing romantic relationships with members of one gender. This makes me wonder, if we're defining sexuality by physical attraction alone, are we confusing the picture? Could some of us experience confusion because our physical attractions are broader than our emotional attractions?
