It's rather annoying that despite the fact that I played this game many times, there are still things that I don't understand. Now, I think I can make a few suggestions that will help make the game a little easier and makes sense.
First, the yoga class. As much I enjoy the idea of a mini-game, there should be a option to automatically win these mini games. Its not that I suck at them, it's just that I don't want to wait like 20 seconds for the next mini-game to happen. It really needs a bit of work there. Especially when two poses look almost exactly the same. There should be some dialogue with the yoga instructor about giving a blowjob. It makes no sense for her to simply offer her cock from the first meeting. It should be in the second meeting where you have at least some kind of cock fetish being developed. It's insane that you need to have oral skills incredibly high to even have that option. I feel that should be the forth or even fifth time you meet her in order to do so.
Second, more clothes, more hair styles, and high heels fetish. Like, that should be a massive boost to your feminity. Different kinds of high heels. One that shows dominance while the other submissiveness.
