You say you don't care but I bet the amount of support your game would get would be much higher if you did. If you're that squeamish that you can't bother rendering male genitalia more artfully then maybe it is you that should be questioning their sexuality. Most people who purvey heterosexual porn can handle seeing a dick and still be confident in their orientation. Seeing a dick penetrating a pussy is a part of what attracts straight people watch hetero porn in the first place. Otherwise they'd watch solo women or lesbian encounters.
A part of the fantasy is imagining oneself as the character being portrayed (obviously for straight men it would be the male on screen who is having the sexual encounter they identify with) And who wants to imagine themselves as being deformed and hideous? It's the same reason why good looking physically fit men are chosen to play most leading roles in Hollywood movies. It's not just so that women can admire them. In general men identify more easily with something they either wish they could be (I.E. a good looking action hero who gets all the girls, or a rich millionaire, a porn star, or many other things).
There's a reason why actors like Chris Hemsworth, Jason Momoa, Keanu Reeves etc., get cast in the roles they do in movies that mainly attract male viewers. It has nothing to do with sexual orientation. But if they cast a deformed scrawny scabby looking dude in a role meant to be heroic, the movie would flop. So if you think that not wanting to see an ugly prick means that someone must be 'gay' is more a reflection on you than anything else.
Looking at the screenshot you can see that she's rendered fine, but the skin on the cock looks like a 90 year old with leprosy. Part of the reason I even pointed it out was because you obviously have the talent to render it better and so it comes across as lazy and negligent. As you pointed out, nothing stops me from discarding the game (I did). But I wrote this so that maybe, just maybe, you could see the psychology behind mine (and other's) complaints. It's a shame really because the game had potential. I liked the story line. Anyways, I won't bother you again. Good luck and peace.
