Seriously I know exactly how you feel. My guy and I have been together for 2 years, he was a porn Fanatic! Like everyday all day [so disturbing]. But after awhile when we started getting serious I asked him to cut it out, cause I was self concious about 'down there', he said "I love the way you look! Porn is just something to waste time".
Well anyway, long story short, i caught him a few times watching porn, and almost broke up with him those times too. His excuse was "I'm addicted" so I took teh addiction away, I put a lock on his computer rating setting, no XXX sites allowed :O) HE said I could if i wanted to, so I did.
I always felt horrible and I felt horrible for making him stop watching it, but oh well, my feelings come before, he was never mean about it though.
All in all, guys are gross and you won't find one guy who never watches porn.:)
