Bro, I decensored your game, and it turns out the protagonist doesn't have any genitalia, which is weird and rather immersion breaking. If you're going to censor it with mosaic, just give him his cock and balls.
And no, don't make excuses with "Oh he's embarrassed that he's got nothing between his legs." He would not have the sex drive to do this sort of shit in the game. The whole point of the game is that he's a pervert, and the only drive to be a pervert is having testicles in the first place.
If you want to justify him being embarrassed, just make his dick super tiny that he's too embarrassed to show it to the girls. But for god sake, give him his cock and balls! It's just weird when he's got nothing down there.
