If a transsexual woman sleeps with men she is straight cause she is a woman sleeping with men. She is just a woman 'trapped in a mans body'. She was born with a biological male body but lives as female and feels 100% female in her head and therefore is a woman - even if she still has her male junk. Not that complicated guys.
If a cross dresser/transvestite (completely different thing) is male but wear womens clothes as a fetish or just like doing it, but are not actually a woman, then sleep with a man, then its gay because the cross dressing person is actually male they just like wearing womens clothes.
Same with a transsexual person who was born female but is actually 'man trapped in a womans body' and transitions to male. If he likes girls then he is straight. If he likes guys then he is gay. Cause he is a guy regardless of whether he was born with a dick or not.
Come on guys, its not that complicated. Educate yourselves and stop being ignorant! SMH.
