It's not as simple as just letting priests marry -- or, more likely, letting married people be priests. There is the whole question of a formation that factors in a healthy approach to marriage and sex, instead of factoring it out and hoping for the best. 
In my view, the Church has no idea how to do that, witness the fact that the great majority of Catholic scholars address sex as a concept instead of as a biological-emotional-hormonal complex. Catholic scholars still struggle to deal with long-decided questions of contraception, when real women are asking whether it's okay to give their boyfriends/husbands "something special" in order to avoid pregnancy -- and perhaps get a good night's sleep in the process.
Show me a Catholic publication that deals with these questions. Show me a seminary that trains priests to understand the decisions women have to take every time they decide to be intimate. Show me one Catholic article about sex not written by a priest or nun.
