Requesting feminist arguments

Question for my fellow feminists...do you know of any articles/journal articles/comics, anything that would explain the difference between women campaigning to be "allowed" topless in public but objecting to seeing boobs on TV? My (male) students weren't buying my argument about one being about equal opportunity and equal status and the other being an objection to objectification ("because you see men's boobs all the time!"). I'm thinking if I complied some links by people smarter than me, it would explain it better and maybe even convince one or two about the differences.

Anything would be appreciated!
