The problem, it seems to me, is that most cross dressers do it as a turn on. Which they know sounds a bit dodgy. Especially as it's kind of self-sufficient. So they try to give their wives an alternative, more palatable explanation. Even saying I don't know is a bit of a cop-out. I've told my partner that it has a sexual side. And she's seen me starting to get aroused if I try on something new. But fortunately, she's open minded enough not to care. But I think she might be quite unusual.
