Be careful what you wish for...
I only mentioned it for narrative purposes. If she still is a virgin she probably wouldn't go as rough as she would go with some experience. That I would find it unrealistic that she still would be a virgin results from the fact that she is a 21 years old blonde bombshell of a women that doesn't seem to have any social inhibitions (as in being shy, being insecure of herself etc.) at all.
Nova on the other hand is portrait as very shy, a bit of a loner and a bit crazy, so for her it makes more sense that she still is a virgin, although with an obviously broken hymen. So going anal (as was suggested) on her first time already, would be a bit of a leap, I would say. If I remember correctly, Cari used one of the more sexually experienced (was it Jasmin?) girls to "teach" some of the less experienced girls (I think it was Judie and Iris?) anal during threesomes. Se could do this again.
It would have Penny fall very much behind. Also Annie had a scene last update and outside of her joining Orion and Nova in that Asian cafe we don't really have any indication that Annie will play a larger part in this update.
And Nova obviously did at some point, because she didn't draw blood in 0.5 when she shoved that dildo inside of her. He probably won't have any blood during sex scenes anyway, no matter if the girl is supposed to still be a virgin or not, so as long as they don't outright say it (like Annie) or their social behavior makes it all but clear (like Luna), one can only speculate.
