An interesting question

[cyba]

..yes, you are gay gay GAY

Or - bi, bi, BI?
That needs clarification too. It appears that most guys who are attracted to LBs are not attracted to guys. LBs, themselves, state that from their experience of guys, as do lots of guys on this forum, and elsewhere. They're adamant. But then there's the question of 'cock' or, particularly, that strange allure of feminity-plus-cock. Cock is definitely in there. Read the posts. It's 'writ' pretty large. Strictly speaking, 'bi' means 'swinging both ways' - guys and girls. But LB-loving guys state they're not interested in screwing or sucking or fondling a male. So, in that sense, they're not bi. But no bio - um, 'bi-o' - female has a cock and 'straight' guys state they're only interested in one thing -'pussy' (and a relationship with women which may or may not lead to marriage and children and a life of domestic bliss - which is not meant to imply that solid, quality relationships can't happen between LBs/TGs and non-gay guys or that, some time in the future, if not now, they might, if they wish adopt a child (a politico-ethical tangle).)
So where are we with our terms?
The extra difficulty is, guys also make the comment here that they're not interested in LBs who have 'trans-gendered', i.e. no longer have a cock which, again, points to that appendage being fundamentally important to them.
Here's another question - what if you found a 'bio' (for want of a better expression) woman with a clitoris 4-5-6 inches long which had a glans just like a penis. No balls, of course. Would that person do?
My guess is - no..it's not a guy.
