First time talking about it

I’m 42 and in the past year, I’ve noticed that when I’m jerking off, my porn tastes seemed to have veered more and more towards videos featuring mmf threesomes. Especially if they include the guys doing stuff to each other. I recently started checking out the masturbation and jerking threads and I am very turned on by watching guys playing with their throbbing cocks... but irl I am not attracted to any of the guys I see.
I am also really attracted to women.
But something about cocks... I would love to try sucking cock sometime... but I’m married and, again, I just don’t seem to be attracted to any of the men I have met. Am I alone in this?
