I wear panties every day and change into a clean pair to sleep in for almost 3 years. I have assorted styles, different materials (nylon, microfiber, cotton), and colors to include different designs on them. I can go more than 2 weeks before I need to do wash. I’ve worn out more than several pairs and replace them quickly. I haven’t bought men’s underpants in about 5 years or more.
I think it’s been long enough were I’m thinking about throwing out all my men’s underwear. I might wear a pair for just a few hours once a month if that. It doesn’t feel normal to wear men’s underwear anymore.
Women panties are just too comfortable and fun to wear. I don’t think the doctor will mind seeing them.
