We exist. I am 100% straight and I prefer non-lesbian female protagonist games. I can't speak for everyone but I can explain my own mindset:
- I don't self insert into the MC instead I see myself as a third party controlling the action of someone else. It's kind of a power fetish.
- Even playing as a brainless slut is somehow more interesting to me than playing as most male protagonists: douchebags, creeps, borderline/actual rapists. I just hate them and I don't want to be the one responsible for those actions. I would rather control the person getting raped than the one doing the raping.
- I like the cute romantic aspects of lesbian relationships but for some reason lesbian porn never appealed to me.
- I don't get turned off by seeing a dick, it's natural to see them in porn.
- I don't see playing as a female and getting into a gangbang as being gay instead I see it as a humiliation/degradation thing tying back to the whole control/power complex.
- Consistent content. It's more appealing to me to see a single female in multiple situations than seeing multiple females in 1-2 situations.
I bet there are other reasons why straight males play this type of games but these are my main ones
Quite the contrary as far as cute and romantic goes: I see cute and romantic traits of straight relationship in real life, regular movies and regular games. As far as lesbian relationships in porn games or other adult media go, I like the uncertain tension between the characters and the dominating aspect of a lesbian relationship. I know there are cute and romantic lesbian relationships too, but I prefer those involving domination and manipulation as far as porn or even other fiction goes.
I also prefer settings, where lesbian sex is still somewhat of a taboo and one of the women involved struggles with her attraction to other women, while the other is more self confident.
Do you see gangbangs as a degradation of the female character or of the male characters? I guess it is somehow degrading to both and I don't get, where a dominant powerful character would be in this scenario. Walking by and quietly shaking his head?
Personally I'm not exactly keen on brainless sluts, at least I wouldn't like them as protagonists. I can seen some scenarios with bimbo fuckdolls, that could be appealing, like a trophy wife becoming her evil queen daughter's sex slave after the death of her husband, but otherwise, I prefer intelligent characters. I don't mind playing as the villain on the other hand, at least if that villain is taller than his mother and not a teenage loser. But whether the MC is good or evil, to me straight porn visually never has the same effect as lesbian porn.
