It's impossible to say.
I don't drink alcohol, and never have, and never will; so I have no basis on which to judge how alcohol would affect me, or how much it would take to have what effect.
I'm straight, so I have no sexual interest in any man, no matter how hard he tries to pass himself off as a woman.
And I've been married, now, for more than half a century. I've never really had any occasion to even think of pursuing anyone sexually other than my wife.
I cannot claim perfect virtue. I cannot deny the possibility that circumstances might exist which would tempt me beyond my will to resist, to cheat on my wife. But so far, no such circumstances have ever come anywhere close to presenting themselves.
