yes, there can be multiple reason why a male would try to have homo intercourse. mainly it is G for P and inceldom.
G for P is no reason, as at least one person must have a real interest. And if the person requesting sex for pay isn't (at least partially) gay himself, he would very likely just have gotten a female escort
It’s a gradual Transition. Humans are wired for variety. Once you fap to enough porn you’re brain will get tired of regular straight porn and start looking for something new. Often that’s just gay porn, or other fetishes. It’s why stuff like inflation exists
Nah, I started with (bdsm) fetish porn, then got to solo videos, then to "normalish" sex and now it's just a mixture which has been more or less stable for quite some time. I never got into fetishes (i.e. something "not norrmal sex") that I did not have in the beginning (when I did not watch porn at all) and I still ignore lots of porn categories like JOIs which IMHO are pointless or gay which I am simply not attracted to. The only category I added in the last years it's VR, but it's a different medium, not a different content.
In fact, the porn I am currently seeking definitely should not be a fetish - it is porn where the male performer comes inside and shows that it's real, but they also cuddle and kiss for a bit afterwards. However, it is not that easy to find.
And I do watch porn since I am like 15, so for nearly 20 years, even though way less in the last 3 years, and also less in the beginning, so you can say I watched a lot for maybe 15 years or so. So I really disagree that you seek out stranger and stranger porn the more you watch it.
