Can married couples have sex for enjoyment and not procreation?

I'm asking because I thought that married couples can have plenty of casual sex for the most part. But then in church I here that the Catholic church is against condoms as with any form of birth control. I'm not married but was wondering. Did some googling and it said the church doesn't really allow sex unless for procreation? Seems that's not what a lot of married couples think. Also what's so bad about condoms? Their smart.
