and I infer that you also have a sex drive which you deem high. And I don't doubt that.
The fact is, though, that sex drive is determined by testosterone exposure, both historically and currently, and high testosterone levels tend to act in opposition to the effects of estrogen and vice versa.
Your breast development, from what you say, hasn't been unduly restricted, so I assume you have breaats of at least average size.
You say you don't sport a m(o)ustache. Do you ever remove any hair from your upper lip? What about elsewhere? -- the most feminine of women don't have leg hair either, though the majority of white American women do.
