not sure what you mean by "closeted straight" do you mean they are in the "closet" when it comes to their "gayness" or their "straightness"?
I can only speak for myself. When it comes to woman my track record is mostly the ones I wanted didn't want me and the ones that wanted me I didn't want, so I always had to compromise, the best I ever had woman wise was "not bad", when it came to personal preference.
Then I met a trap, (s)he literally tricked me into having sex but I didn't care because I was young, dumb, and full of cum.
Traps represent large amounts of unbounded sexual fun without any fear of emotional bondage or rejection, you are basically having sex with another version of yourself who is pretending to play the part of the female solely for the thrill and theatrics of it, yes they're wired that way, but they are still men and think like men and have the same autistic viewpoints as straight men.
Also, I'm not saying it's impossible for men to form emotional/romantic bonds with traps, but it will be met with some subconscious psychological resistance that the they will have to overcome.
One thing I was never sure about is if liking traps was an alpha or beta trait, I could easily make arguments for both cases, in the end I guess it's neither and that's just a silly way of looking at things and is just more of us trying to label and classify everything.
Traps are my number 1 sexual fantasy, and yet I desire women with more emotional longing, it's a confused state of affairs but I get used to it.
