Jo.. some guys like their woman to wear their clothes.. It like the woman saying "I like your smell or I feel you around when I am wearing something of yours.
Some high school girls wear a flannel shirt their boyfriend used to have. The shirts are soft and warm. It is also a bonding thing. My D17 at the time, wore her boyfriends shirt.
I also like to share anything that feels comfortable to me. I have some soft cotton under shirts and I think they would make good night shirts to sleep in but BB does not see it that way. Its kind of like, " here have a taste of this new coffee, it is really good. Anyway that is how I feel. You should know Andy better than me.
I do see the shower scene too. Almost every boys dream. Some of us guys never grow up in that department.
