I've never shared a crashpad with FA's, but those who have told me "don't do it." On subjects I have little experience on, I tend to heed advice pretty well. The obvious facts are that, if you are married, you're wife may not be fully understanding of sharing close living quarters with female flight attendants. Besides the female FAs probably don't want you around either. In the case of male flight attendants, it's obvious why you might not feel comfortable. BTW, most female pilots get together in their own crashpads and don't share with males. Crashpad life sucks, so don't make it harder than it has to be.
