I would highly suggest that if your Goddess wants you to do this, then you should design a Spell for yourself (after all, YOU are the one desiring this intention, not anyone else) to call upon your feminine side. Best advice I can give to you. But I do wish you luck with your Spell that you are going to fashion for your intention.
Well, there is the maiden, mother, and crone feminine sides. There is a large spectrum to femininity. Which one are you particularly looking for? There are plenty of female archetypes out there, but if we don't know what aspect of the female you wish to focus on, we can't help you very well. The other question I have is what cultural deities are you most comfortable with?
When people ask about feminine archetypes, my first instincts is to suggest the Roman Venus or her better known predecessor the Greek Aphrodite. But there is also Astarte (Sumerian), Isis (Egyptian) etc.
Going drag is always fun, but I'm thinking more of the sexuality side, like Venus/Aphrodite, but I like Artemis and Apollo, maybe I should call Apollo for a spell of loving from men? Because he has had his time with men but in Orions legend he got very offended by him saying that. So maybe Artemis since she seems the closest to LGBT? As well as having closest amount of personality traits to me. So idk, I need to invoke more of the sexuality of the female than anything else. Sorry this is confusing
I agree with all the above posts. If you are thinking sexually, start with sensuality. As was said, indulge in scented baths, expose your skin to the moonlight, dance! Wear clothes that are sensual, sing along with the music of our greatest female vocalists. Take care of yourself, paint your toenails, brush your hair, wear jewellery in tribute to female deities. Fill your home with flowers. Good luck! :D
