MarkoH01: If you are turned off by< a game with sexual content maybe you should not buy games with "LUST" in the title? Also, I don't have any tits.
I haven't played the game so I can't confirm this, but other users in this thread have stated that the AO version of the game includes scenes of rape. Many people are extremely uncomfortable about the topic of rape entirely and they certainly don't want to see it, fictional or not. It is entirely possible to enjoy horror and to enjoy sexual content while simultaneously wanting to avoid seeing scenes of rape.
For reference, the disclaimer on the Steam store page for the AO version is "LUST FROM BEYOND contains sex and nudity, extreme and sexual violence and it's not suitable for viewers under 18". I think it's safe to assume that when most people hear the term "lust", they don't think of sexual violence.
As for tits, yes, you do have them; all humans do. Yours may not be big, but you still have them. Not-so-fun fact: Men can get breast cancer.
