My boyfriend seems to have little interest in me anymore . We have sex every couple of weeks , which he seems to enjoy but he never ever initiates it . I have discovered he still has photos of his ex girlfriend on hs phone , laptop and in some boxes and further discovered he has been looking at porn , which he has never told me . He constantly tells me I look good but he has just returned from a week away where I bought loads of new underwear only to not appreciate it . He sent me an email saying could I put it on for him , bu the past two nights he has said he is too tired to do anything , but I notice he is still looking at porn . He told me yesterday that he likes having sex with me and keeps apologising when we don't but I feel like I have been replaced in his affections . Is it normal for a man to still have photos of his ex 2 yrs after they broke up ? And even though I have asked if he maybe doesn't have them anymore says OK but doesn't get rid of them ? Why does he keep emailing and texting me saying how amazing I am and that he loves having sex with me yet when he is with me , he makes not a move in the slightest ? He says he doesn't like kissing either . I'm very very open sexulaly and have no prob with him watching porn - I just thought he would have told me about it .
What do people think?

How old is he and how much stress does he have at work. There is always the possibility of medial reasons that increase with age.

Don't assume its you, or him doing something on the side.

Most guys love their ladies wearing sexy underwear. In fact I buy all my wife's underwear for her (except bras, she does that), she loves my taste and loves thongs. And she is in her 40's and still looks better in a bikini than most women half her age at the beach.
