Monica has a reduced libido, yet she is a healthy, non-frigid woman who is capable of having an orgasm on occasion. Obvious things that have been discussed many times before. I realize that a love of hentai fantasies such as "sex addiction/sex obsession" exists among a good portion of players, and that's fine. However, Monica was created by the Dev as she is, and I personally don't see the point in changing her. If she stops freaking out about her orgasms, that's enough.
And obsession with sex, magical aphrodisiacs, brainwashing and similar "semi-magical" themes are better left for other games. Years will pass, and other developers will look up to Fashion Business as the gold standard and almost the only game where the most beautiful female heroine didn't turn out to be a banal "happy slut".
