The question bothers me at that many levels. In "normal" persons, talking about genitals is never a polite topic, and only acceptable if you have absurd levels of confidences. As a man, have you ever asked somebody (in normal conversation) how her pussy looks like? Sure, between men they seem to carry a placard saying "ask me about my dick", but to me... Having a dick stills makes you a man and you don't mind talking about it? Since you are not a true woman you don't need to show absolute politeness?
For me unless there is an heightened level of trust and confidence, I don't think there is any politeness in straight asking me what am I going to di with it. Sure is, fascinating, but... Not polite.
On my answers, sometimes I offer myself to describe them all the process. That surely make them regret asking that, and some look down to themselves with fear. With women, I've never been asked about it unless it was a really close friend. With men... All the time.
And despite what I thought in the first denial stages, I'm the kind of woman that wants the full package. Most of the time I can blur it from my sight, but I never spend too much time in front of a full sized mirror or in the bathroom without a towel. Over time, it's become something I deem important in my life. Maybe that is why I get so pissed off... Who knows...
