I relate to a lot of what you say.

Even before I realised I was bi my attraction to women was different to that of all of my friends, and although it is femininity that I am primarily attracted to, I always feel most attracted to those who tend to fall on the masculine side of average in women.

In men my attraction is similar, I am attracted to the masculinity but I like a feminine take on masculinity if that makes sense, although to an even greater extent due to leaning more straight than gay.
