I have had a vaguely similar experience, I did get aroused, I did enjoy it. I was married to a woman for 11 years and never had difficulty getting an erection, even when I had been drinking. I suppose you must be exclusively gay, I must be closer to the middle of the Kinsey scale.
My life experience says bisexual but as of today only guys turn my head.
I tried having sex with woman a few times and never an erection. I am quite sure that it would not be possible for me to get one. But, I don't always get erections for men either.
Not only am I far more physically attracted to men, but I totally cannot acclimate to female plumbing.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
