My BF is wearing some girl's clothes?

Yesterday I posted that I had found out that my BF had bought and was wearing some size 10 long Mudd jeans (girl's obviously). Most of the respondents thought this was fine as long as they fit and looked ok on him. Now last night he came to bed and he had on VS satin PJ's - he said he likes the way they feel. This is getting a bit wierd isn't it? Do any guys out there wear satin PJ's or does you BF?
