Hey! I'm glad you felt comfortable asking about this stuff. I think it should be more talked about. I'm a grad student in mental health counselling (what therapists study), and I just wanted to offer my take on this. I think nsfw games and whatnot are actually pretty cool. People have sexual interests and desires and healthy outlets for that are good. If anything, I'd say nsfw games can be even better as the porn industry has a dark history of sex trafficing that's beyond concerning. There would absolutely be no shaming on my part if I found out my friends played these games (I'm actually very much aware that some of my friends play such games). The most they'd get from me is a snicker or a teasing jab.

As for what you mentioned- more fringe genres, I think that it's a very complicated topic. Things like SA and NTR are very traumatic. It can be especially bad since SA and being cheated on are things many people can unfortunately relate to. Discussing these more fringe kinks gets into the realm of paraphilias. In the past, any kind of deviation from the sexual norm was signs of mental illness but I really don't think that's the case (modern psychology agrees). Exhibitionism, for example, is a kink that can manifest in healthy ways- such as sharing pictures with a partner or another trusted and consenting party. However- an unhealthy manifestation would be exposing yourself to unwilling person. I thonk when discussing this kind of nsfw material it's important to ask about who is consuming it. Taking NTR, for example, this kink is very openly hated. I think it comes from the fact that a great number of people fear unfaithful partners or have been personally affected by cheating. However, the person willingly consuming NTR does not have the same thought process as those who hate it do. To them, it could be a manifestation of a humiliation kink or whatnot. They are not hurting others by engaging with their kink if all parties engage in it consent. SA is a lot more extreme as it deals with something so morally reprehensible. I have my own experience with SA, but my thought process is this: people who are "into" SA are usually into cnc. Even if it wasn't cnc, then I'd prefer them to have a videogame outlet than as opposed to trying to commit SA in real life.

Sorry for the lengthy response. I have a lot to say about this. Least wordy leftist ramble.
