did you know that studies,(take this with a grain of salt)say that when guys watch porn it releases endorphins,kinda like when someone smells popcorn or rides a rollercoaster? seriously though,I personally think that if he respects you,If you tell him that you feel uncomfortable with his porn watching, then he will stop.though,you can open up a wonderful new chapter in ur relationship(and have some input)if you suggest that you watch them together!!, For one thing you guys can have intimate times,for two you can see what floats his boat,and you can show him what floats your boat,could be a win-win situation. At the least you wont have to worry about him doing it behind your back....g luck
