As I'm not out yet I haven't experienced that personally but I can totaly see that as being afirming. I would hope though, that it has nothing to do with being viewed as sexually attractive. In boy mode I hold the door for any woman regardless of age, size or attractiveness. It would be nice if, when the roles are reversed, people would afford me the same courtesy.
I'm not sure how I would react to sexualy motivated attention, I have zero experience with that in either gender role, at least not to my knowledge!
