If thats the case then i kinda doubt your straight claim...but thats none of my business. In straight porn games i only care to look at the female so i prefer male mc as vague shape like this since i dont have to look at him and because he has no shape he could be anyone's avatar.
Genres and specific kinks aside, in graphic porn games I care about the visuals, as well as playability and lewd charge. If you're living in 2021 and somehow are able to eroticize this steaming pile of low-res graphics with a transparent blue blob pouring itself all over what appears to be a 12-year old's best effort at drawing a nekkid schoolgirl lefthanded then I kinda question your taste in art.
Depersonalized depiction of male lust used as aid to those viewers who think that being aroused from watching faced men other than themselves having sex with a woman is somehow not entirely straight can be executed much much better than what this 'game' offers.
By the way, do you realize that the author of this game is a male? And the things, persons and situations he depicted are only figments of his perverted imagination? And he published this game with intention of reaching male public, preferably as perverted as himself? And this is true for almost any other porn game, or movie or smutty literary work. So basically, in 99,9% cases of porn experience, male players/viewers/readers are fapping to graphic made-up stories communicated by other males. Doesn't that bother you?
