Just a thought, but have you done any reading on asexuality? Based on what you've written, it kind of sounds like you might be heteroromantic (as in, romantically attracted to the opposite gender) but you might not necessarily be sexually attracted to them. Heterosexuality and heteroromanticism often go together, but not always. Some people who are asexual desire to be romantically close to others, but have no interested in sex.
Don't know if you think this sounds like your situation, but in case you're interested, here's a link to the asexuality wiki:
