To tranny or not to tranny?
Wow, I'm impressed (and pleased) with how polite everyone is being with this thread. I think it's a fine line about being gay or not. Personally, I'd say bisexual. You aren't necessarily seeing a tranny for the cock but the illusion of a girl with a cock and as previously stated the knowledge that greek is definitely on the menu. The girls (that's what They prefer to be called) certainly look the part. At least until the panties come off. So who cares about labels. If it gives you pleasure and you want to do it what's the difference if people think you're gay or bisexual? Besides, are you really gonna tell anyone outside of this community? And clearly we don't care....
No one should ever be judged for what they are into. To answer your question, it 100% makes you bi. On the other hand having a female use a strap on you isn't bi because it is a female. FYI one of my besties is a tranny and from what I have learned in order to be passable you need to take hormones which make the plumbing have some issues with working.
I would never judge someone for their orientation or preferences, I myself am bi even though I would never date a woman because they are just sexual objects to me (go figure). With that being said, please be careful with everyone you see in regards to STDs especially if you chose to go the bi route and see a male/ts only because of the fact that the homosexual community statistically has much higher levels of hiv/aids among other STDs. When I got my medical certification I had an internship at a clinic in a big city near 3 gay bars and a club... Oh dear god the stories I could tell.
