My boyfriend of eight years has started to watch porn and try to hide it from me. I understand guys watch porn even ones with girlfriend's but he didn't watch it regularly until just recently and it tends to be as soon as I walk out the door, and even more so right after we have sex. While it is normal for guys with girlfriend's to watch porn, is it normal for them to watch it right after they finish having sex? Also, he won't watch it with me and like I said even though he knows I know he has been watching it he still hides it. I tried to show him it is ok by watching it myself and showing him that I was watching it but that did'nt make a difference.
