I am curious why you refer to the sexual addiction model as "hapless". Just for curiosty (certainly not a scientific inquiry) I recently visited some websites with personal ads. I found it surprising (certainly not what I expected) that well over 90% of the ads for "women seeking women" and "men seeking men" were about sex, generally about the less than usual sexual practices, with words like hot sex, exciting sex, sex everyday, son wanted for bear, woman for hot threesome, and so on. I then compared these with the "men seeking women" and "women seeking men" ads and could not find one personal advertising for sexual a relationship. Most were looking for friendship, companionship, possible longterm relationship, sincerity, honesty, and so on. Again, although not the least bit scientific, a well designed survey of this widely available information might be one clue regarding sexual addiction as part of homosexual behavior. The hypothesis hasn't been proven or disproven as far as I know. Something to think about.
