About the daughter, ok, was simply curious :)
About the wet dreams
, not too much research had been done on them and different people experience them in different ways. Some people never had/have them, some have them even more frequently than you, and some have them/stop/start having them again. Some say that if they masturbate more often or have sex more often, the dreams lessen, while others claim that the dreams only lessened with age.
If they are not hurting you or your wife, or affecting your sex life, I would say to enjoy them if you can, and it's possible they may lessen in time. If you experience any kind of pain or swelling down there, either in your testicles or in the perineum
then you'll want to talk to your doctor and get checked out. Other than that, I would say you're probably lucky, and very in touch with your sexuality. There's not a way to really control them, some say you can masturbate before you go to sleep or have sex before you go to sleep and see if that helps.
