Imitate feminine individuals: C-3PO, Jack from Will and Grace, David Bowie. :D But then you'll be pretending to be somebody you're not. Just be yourself. In the end, you'll find people who like you for who you are, rather than people who like you for who you're pretending to be.
Just be yourself......if no one likes that then that's their loss !! I'm a 14 year old girl and I have 75% guy friends cuz girls start to much drama. I act girly and classy, but I still know how to hang with the guys !! Hope this helps and good luck ! (:
