OK for some real life reality check.
I have/had a gay "friend" he must have for year been after my booty because he obviously sussed out may feminine side (even before I WANTED to notice).
Never gave up for years. I never could be gay so we came to some sort of "armistice" yet he ALWAYS tried (just a little).
When all hell went loose and I transitioned he was the first person I could actually speak too but learned pretty fast that it was NOT his "cup of tea".
So still learning (of sorts) don't we all, I one day decided to hop into the "cold water" and have sex with him but being all girlie self. It left me pretty cool, really, tried but did nothing for me. It did some for him for sure but hey, then so what.
He tried to get me into some of his gay videos but it either but me off or left me plain cold. He sensibly has now accepted I'm a t-girl and not gay. Tough, but good lesson for him too. Still tries to be friends but the flame, his flame, finally died.
Gay men like penis and not girl-bits. I had small boobs then and right through it all flaccid penis (still being pre-op). Thankfully he left my "extra" alone and busied himself with "servants entrance". It was for all intense and purposes just some labour of compassion on my side. One time, and thank you please no more.
But mind you in some small way I did feel of having myself let be used. Only noticed later on when my "girlie" instinct was jilted by him trying to treat me like some buddy thing. I sure didn't like that at all. He still tried to see me as some f***-buddy like typically gay male sex perception and hell I sure ain't.
So, I know there is no way that I see any connection between t-girl and gay male. Gay male is much like straight male but not interested in girl-bits. Simple as that.
