Nah nah nah.
You might be able to fake it a few times but long term, the plumbing won’t work. There is no way I could have a long term sexual relationship with a man, even to fake it. I’m just not wired like that.
So when a gay man says he was married and had 3 kids but was never sexually attracted to his wife, I call BS. The evidence runs to the contrary.
This guy had an 8 year relationship with a woman. But he was never attracted to her? Bull-oney.
But what about John Travolta? Tom Cruise? Michael Jackson?
I often think IMHO, that you can be initially attracted to a spouse, but factors ranging from attraction to another woman, porno obsession, to same-gender attraction can constitute overcoming the base one with time. All evidence here is that if she thought him straight, well, sounds like they did a lot of stuff together before he came out.
