I'd want to see what it was like temporarily, and then if I liked it sure let's do it permanently. But ONLY if when changed it was like I'd always have been a woman to everyone else.
Basically even if I tried it out and preferred being a woman I wouldn't want to live with everyone knowing I had changed my sex!
I'm quite content being a man currently but yeah I'd definitely see what it was like given the opportunity, assuming there was no negative consequences, why wouldn't you.
