Sexual Cross Fashion?

My sociology professor just confessed that he would do anything for his wife in terms of sexual experimentation with clothes. He said he would wear anything – a school girl outfit, a nurse uniform, a business woman’s outfit- to role play the part if it so fancies his wife. He is so comfortable with his sexuality to the point where he felt that cross-dressing would not affect his heterosexual relationship is interesting. I’m curious to know if others would do the same… If people were comfortable to doing so, it would be less taboo for guys to dress like girls. It’s okay for any girls to dress like guys, but it’s only acceptable when male celebrities dress like girls? I don’t think that’s fair.
