Jock strap -dudes only-?

I walked into the locker room for bball the other day and my whole team started puttin on jocks. i had my compression shrts and i asked my friend later in private why everyone had jockstraps now and he said that now that we were in h.s. that no one wore compressions and they were a jr. high thing? i gotta go get a jock. he said they were expensive cause they are popular again. where do i get one?
