Unless your husband is attracted to men then he's not gay. Transgendered women are not men and having anal sex doesn't make a man gay either. Regular women do this with men with a strap-on.
What is it then if a man has sex with a female to male transgendered who still has a vagina? Straight because he has a vagina? No it's gay because he was attracted to that person because of them looking like a man.
So your husband probably isn't gay or bisexual. Some straight men are open minded and can just appreciate a transgendered woman and the sex they provide, for others it is a fetish.
So the answer this years old question:
No it's not gay or bisexual if a man likes shemales, has sex with them or watches shemale porn. If he's attracted to the female form then he is straight.
Actually those theories of sexuality being fluid were proven false. Some may change sexuality over their life-time or be on a scale but there are others who aren't. What's wrong in thinking that there are people who can solely identify as 100% straight, bi or gay? There are such people.
Enjoying anal penetration from a strap-on or shemale doesn't make a person bi or gay. The g-spot of the male is something that simulates them so why is it wrong to enjoy that?
Unless a man is attracted to another man then he is not gay. Shemales are not men and most straight men are attracted to them because of their female appearance. While it's true some shemale lovers may be bisexual, it's also true that others (in fact the majority) are straight and identify as such.
Straight men can have anal sex with a shemale and receive it from them without being bisexual or gay. Believe it or not but straight men can enjoy anal simulation too.
Unless you're attracted to a man then you're not gay or bisexual. Most shemale lovers see the shemales as women (which they are, transgendered women in any case) and that's what they're attracted to.
How can he be gay or bisexual if he only likes shemales? Shemales are women and straight men can enjoy anal intercourse.
You clearly have a problem with transgendered people.
Shemales are transgendered women. The straight men on here are still straight because they are not attracted to men but women and the female form.
So what if they enjoy anal intercourse? So do men with genetic women or does having strap-on sex make you gay? You're an idiot.
By your logic, sex with a female to male transgendered person who has kept their vagina is straight even if the person in question looks completely like a man. No it's gay sex then.
