What do you mean mostly targeting teenage males? Let's look at testosterone by age okay? From 17 all through man's twenties testosterone is consistently at a certain range. This is where men will have highest sex drives over the course of a decade. A man can increase his testosterone through good diet and lots of exercise. http://www.healthline.com/health/low-testosterone/testosterone-levels-by-age#adolescence3

The more testosterone the higher the sex drive in a man. Whenever people try to claim it's teenage males I'd have to disagree. It's usually men at the ages of 17 and up that are the most horny.

Seris isn't oversexualized. All you see is some cleavage that's it. Plenty of females have cleavage showing nowadays. I think that's actually pretty messed up how you think cleavage is oversexualized even when so many real world girls do it today.

I'ts FARRRRR from a hentai game, very far. There are no explicit sex scenes,lol. None of the females are overdone though... If the females are overdone then so are the men with their muscles.
