Yes, I understand that, especially in an endeavour as time-consuming as a VN created by a single developer. And that case can be made for many of the VNs in my signature, not all options are for all of the players. I've seen discussions derail because the fanbase gets very divided on what sort of content they'd like to see.
But on the other hand, what we've seen so far in WVM in terms of actual sex has been pretty Vanilla, aside from the TShauna path and that was a choice the player was given right from the start. I'm saying a little variety wouldn't hurt and by that, I don't mean a larger variety of girls, but more variety in the sex acts performed. Which could go two ways.
1. Increasingly kinkier sex acts with individual girls (with sometimes other girls watching) OR
2. More combinations of MC and 2 (or more) girls, or 2 (or more) girls with MC watching OR
3. A combination of both.
Variety is the spice of life, and yes, unfortunately that means more work for the developer. But it could also help to expand the existing fanbase.
Edit: PROVIDED that it's all optional of course
