I think you should give players more options and information. Sometimes I get to choose whether or not to do something or to react on something; other times, the choice is taken away from me due to some unknown variables. For example, I don't understand why my speech or will check failed. I sometimes can decide whether to do something or not. I would prefer to choose whether to give a lewd or normal answer. Most of the time, all these things happen automatically. I would like to be able to see the stats and the chances of the answers/actions I can choose more easily.
Apart from that, it's interesting to play. However, you should reward normal (virgin routes) playthroughs more. I'd like to try not to be an easy catch, which is kind of boring and absolutely not worth it. It would also be better if the protagonist was more embarrassed and ashamed (as a former man) and needed more time to become comfortable with or addicted to lewd acts or his/her appearance. I prefer a slow corruption/change of the mental state.
