I like to have the option -- but the idea of 'virginity' in an AVN is always a bit awkward I think from a storytelling perspective.
Not so much if it's more of a dating sim, and there's build up to it, but when it's a harem style 'every female wants to bang the MC 2 secs after meeting them' it just never makes sense to me. You gonna tell me 11 women gonna hold on to their virginity for 18-21+ years just to give it up willy nilly out of the blue? lol
At that point blood no longer adds to the immersion, because it's not logical they are all 'virgins' anyway.
If it make sense in the story that she is a virgin, then yes I am fine with seeing it. But it is not like there has to be. What I don't like is when the girl is confirmed to be a virgin and there is not explanation has to why there is not blood. Because there could be a lot of reason why I virgin won´t loose blood on her first sexual intercourse. But if you don't tell me why, I am just gonna think something is off with the realism of the scene.
