How can i look less straight...more ...?

There really isn't one look. I think a lot of s are more open to their masculine side because when you come out of the closet, you also step out of heteronormative society. Like Kimi said in your video link, when she was part of that heteronormative culture she was fake, an super feminine to attract guys. I bet there are a lot of straight women who are fake too, and would be laid back, an bring out their masculine side if they woke up to it. Also there are plenty of women who are feminine. I mean, just be yourself an that's fine.
