A wizard offers you a deal.You can instantly become a biological girl. You will have the face, voice, height, body type, etc that you consider absolutely perfect.
However, this comes with a caveat. You must always cheat in your relationships. For each year that you're in a relationship, you must have sex with five other people besides your partner or you'll turn into a guy. This cannot be an open relationship, it must be cheating.
Do you accept?
