wet dreams are normal not much you can do about it, except if you see your hubby having a sexual dream....you should take advantage of the situation
I know I am weird that 95% of my fantasies involve my wife, I am a rare breed. My wife claims she has no fantasies and when she uses her vibrator she thinks of nothing....I am like ok honey...no George clooney? no Bratt Pitt??? LOL
Again nothing wrong with looking at the menu as long as you do not order.
Your hubby was probably dreaming about you anyway....ie the night before.
