I definitely agree with the no nudity option. Not everyone wants to see things or even have a sexual relationship in their game. I myself am asexual and a SA survivor. I for one, would be very appreciative if there were at least an option for no nudity. I would especially like it if there were a romance path that you could take with the characters where you still romance them, but refrain from anything past kissing, hand-holding, hugging, etc. Perhaps not with Astarion though...he seems to be a very explicit character as far as that goes. With that being part of his personality, he may be only character without the no sex option (in my opinion.)
I just would like full freedom to interact with these characters as I would, or as my character would. Most of my characters are more serious characters and aren't really interested in sex, although romance is not off the table. I understand that some people would prefer to have these types of relationships with the characters, but others may not. In fact it may be almost triggering for some people, especially SA survivors like myself. I don't like seeing sex scenes, but it doesn't trigger me. For others, however, it could trigger panic attacks or worse.
That's a good point, and thank you for sharing your perspective. That it could be traumatic for some players is definitely yet another good reason to enable users to opt not to see sex scenes, so that those gamers aren't totally barred from the safe bits of the romances. And yes, it would make sense for player characters to be able to say that they like an NPC and would be open to a relationship with them, but not sex. As you say, not all the NPCs are necessarily going to be into that, but our characters should at least be able to express their preference, and I don't see why at least some of the companions wouldn't be open to the idea.
