ADOVAKKERWomen's Underwear Low Rise Lady Micro Smooth Breathable Briefs Hipster Panties Multipack Printing J-S1

Above average package would these work for a man?

How the spandex around the butt? Meaning does it hold all day or does it start to get lose & then you just feel like your wearing baggy undies.

I canceled the purchase but my money was not refunded how do I solve this problem?

Can I put these in the dryer?
