Hi! If you find it useful, I would class you as "genderqueer". You can ID as female and still explore your male leanings with your current partner or with others and have a lot of fun.
It sounds like you're very sensitive to your partner's feelings and reactions, which is awesome. I hope you also have space to express your needs and desires?
