How many straight guys would consider going bi/gay at a woman's request?

Most straight men would not(although I wish they would). If the man is fairly straight, but is on the bi spectrum he might be into it. From my experience.

You'd be surprised, I've talked a few guys into doing things they would never imagine trying. There's something biological that when you're horny the "ick factor" almost completely disappears.

Sucking and fucking a man in front of his wife is so hot! We put on one hell of a show for her! She joined in, and it was amazing!

I would do a threesome

Yep as a closet bi I’d be all over that!

The odds of finding the right other guy, that isn't intimidating, too attractive, too into your wife, wife too into him, not physically intimidating, perfect stranger yet safe, Equally or more open to whatever, etc. that realistically this would be a near impossiblility.

Sure, some of you would say, naw, I'm not that picky. But that tells me you haven't thought about this before. We all have insecurities that would riddle this situation all over the place.

If this was a porn, sure simple. But real people, with real needs, and insecurities, and things that threaten them openly or secretly..... This just seems to be too out of reach for reality.

NOW. Sure, if your life is a cluster-fuck already, then most the above don't matter. For those with a average life, it does.

You can not just "go bi/gay", people can not decide who to be attracted to.

I would not do that, and would be disgusted at the thought of a woman (especially my woman) fantasizing about me doing that.

No strait man will ever be gay for any woman. I have done a threesome with two women. Will never allow myself to be naked with another dude. You sound like you're gay and trying to persuade another woman to agree to for you to do it with another guy.

This is a loaded question. Most guys will do anything a woman asks them if they think they can get somewhere with the requesting female. Guys are stupid like that.

We do it both ways. We both enjoy cock and pussy equally.

I could say that sexuality is ever expanding, if one is willing. That means that technically anyone can develop almost any kind of fetish (thats why porn is such a rabbit hole).
Straight men are inherently disgusted of having sex with other men (and sometimes even of another male body in general, depending on cultural factors). That being said, if the guy is open minded and with the right kind of stimuli, you could convince him of trying it, but it would be the culmination of a process.

If you want to do it, id recommend trying to watch porn together that has a very feminine transexual (has a dick) playing with his ass. Then gradually increase exposure to masculine traits, like less feminine ones, or transexuals fucking eachother, and finally gay sex. Once he's used to watch gay sex, you could ask if he would be willing to try it.
Dont jump ahead, though, or a "WFT? NO!" is the most likely response

None, straight means straight.

*see “what words mean”

Threesome's a maybe, since they could easily just not engage the other guy if they don't want to. The balls don't have to touch.

Straight-up gay sex would be a definite no, I'm sure.

Sounds like a great way to get AIDS, give it to your wife and possibly conceive an AIDS baby.
