I find pantyhose to be very sexy. My gf doesn't like wearing them as she says her feet get super sweaty. I never heard of this?

I only wear thigh highs because my other half loves them but yes in the summer time they can make your feet sweat in shoes. Usually i only wear them in winter or just put them on for him and take them off after so i dont have to wear then with shoes.

Get her to wear some black lace silk stockings when you are playing together

You need to put on a pair and wear them around for the day so you can begin to grasp how restricting and uncomfortable these are.

Yeah? So? Who cares?
