boyfriends and porn

i feel stupid for even asking this... does anyone else get insecure when they see that they boyfriends watch more porn then they try and have sex??? now heres some back story... my boyfriend and u have been together over a year now. i recently found out my boyfriend was on a dating website and talking to other very cute and much small girls than me. now he never met up with any of these girls but he did flirt with them and accept nude photos. i deleted his page and have been checking his phone daily. it was the only way i felt comfortable continuing the relationship. well since then his porn history and more than doubled. and he knows im okay with having sex alot thats how the first few months of our relationship went. and he still continues to say how much he loves having sex with me. well then why so much porn and why so little sex. he watches it 2 or 3 times a day but only wants to

have sex 2 3 times a week if that. should i be offended cuz i tell you what i feel horrible and gross and ugly. i want to punch him and call him a perv. im okay with watching a little porn but not when it happens more than my sex life. maybe im over reacting... opinions???
