A lot of times I'm not sure what's definitively feminine or masculine because the social norms tend to shift. This is stuff that feels feminine to me though:
I love the gothic side of femininity. Pentacles and black dresses and dark makeup and horror movies. One of my best friends is pagan, and I'm in her coven for moral support and the much cooler Pagan holidays (Yule > Christmas). I'm actually not embarrassed to say I was big into the Twilight craze in high school and I still love bands like Evanescence and Lacuna Coil to this day.
I think we're at the point where fantasy novels are female-coded. I too get the feminine urge to slay the Witch-King.
Is hiking and camping a femme thing? I'm a nature girl 🍁
Aside from that, sewing, gardening, manicures, aromatherapy, Aggretsuko, fall, pumpkin spice lattes, and rom-coms if they're written well. (My fave is "The Holiday.")
