I've been curious about the same sort of thing.
I'm fine with anything someone wants to do in private or with another consenting adult. I can see how crossdressing can be very sexy. I think sharing that with a partner must be great. I also don't have an issue with masturbation in a relationship for the kinds of reasons Sandra-leigh mentioned.
The thing is, I expect masturbation within a relationship to be of the relaxing quickie variety, or a bit of porn surfing on an evening when I'm not around. Crossdressing takes time, money and a degree of committment that doesn't match up with what I understand as a simple natural urge for sexual release. I guess it's what Reine said about the femme side seeming like a mistress. I think crossdressing is sexy, but if someone's primary motivation is sexual, then it confuses me because I don't understand going through such lengths for a turn-on. A pair of panties is one thing, but wigs, forms, heels, a whole wardrobe… it doesn't add up.
The other part of it is going out. I find it kind of off-putting that people who dress primarily for thrills and sexual reasons (and not just to express a feminine side) would even leave the house. It's seems like it's involving non-consenting people into a kind of personal fantasy. (Exceptions for clubs or places where it would be acceptable, of course.)
I guess the NCAmazon's post interests me in that maybe it's that the sexual aspect is there, but seen as a hindrance in public? That would make more sense than the sometimes disturbing impression I've gotten otherwise.
