Some providers advertise that they offer a session with a male friend as well.  You menoned "gay" and "straight", but thewre are plenty of men who are bi-sexual or bi-curious and onle once in a lifetime want to act on it.  Doesn't make them gay by a longshot.

If a woman scratches your back, it feels good. If you're blindfolded, and someone scratches your back, and you don't know if it's a man or a woman, it still feels good. The point is, it feels good.
I have had clients, as well as men in my personal life that want anal play performed on them. It's not gay. It's a feeling, a sensation, a pleasurable thing, just as having a massage is. Now, sharing that with another man, or a TS can put that into a different category. The important thing is how you feel about it; how you enjoy it.
I would say, find a provider whom you know will do that with you, one who is quite experienced with it, and see how you enjoy it. If you have someone in your personal life that shares that with you, you're one lucky guy.

I'll never forget this one time my daughter asked me to talk with a friend of hers who had 'shut down', wasn't himself, not talking, acting suicidal and freaky. Come to find out, he told me that he'd gotten drunk and his roommate had some friends over (guys). Most of the guys left for awhile, leaving him alone with this one friend of a friend, who was also drunk. One thing lead to another and they ended up having sex. He was freaking out over the experience, thinking he was gay, and was suicidal because he didn't think he was! He was hating himself because he ENJOYED it, and thought he was a freak! I told him he enjoyed the FEELING, the experience, the orgasm! Things that feel good feel good! What does he lust for - men, or women? Women! I'll never forget the look on his face when he realized he was 'ok'.
Of course, everyone's different and has to be comfortable in his/her own skin. I don't have a problem with gays, so please everyone, don't 'read into' anything by my story here. I AM saying that one needs to relax, be comfortable and true to yourself, and not try to pigeon hole or label things.
And certainly, don't feel freakish or 'gay' because you have the desire to try it.

If it is not part of a womans body it stay's out.

Why ask "Is it Gay?"  Are you filling out a survey that want's to know if you ever did anything "Gay".

Do what feels good, and who cares about labels.

But, if you must...  The term gay or homosexual describe a preference for being with a partner of the same sex, so there is an easy way to answer your question.  It has nothing to do with physical activities...

So, it's only "Gay" if you were attracted to men when you did it.

Hey look at it this way, if you want a guy to do it, maybe, if you want a woman to do it , its kinky but not gay. Not any more than enjoying her slip a finger or two in during a bj, which by the way is quite nice.

The homophobes will say you're gay for just bringing up the subject.
Tell me, if you eat spinach with your steak, does that make you a vegetarian?
If it feels good, or bad in a good way, or however you enjoy it feeling, it's your business, try not to worry about how others will label it. Interesting, though, that you who are curious about how you'd be labelled are quick to label those playing with a TS as gay. Careful, those glass houses are fragile.

Sex is nobody's business but the three people involved.

Party on, Garth!

I don't know if its gay or not.......Personally i aint gettin drilled...ever...... lol
