Usually catholics believe that you shouldn't be sexually active until you are married. On top of that they believe that men shouldn't masturbate because they "spill their seed". So what then do they think about a married woman masturbating? She's married and can be sexually active and also doesn't release an egg when orgasming or anything.

Note that I know all catholics don't believe what I said but most fundamentalist Roman catholics do. So does anyone know the answer from the perspective of those people?
