<human>: I found many posts about porn in relationships but nothing with this reason in particular. My BF and I are now in a serious relationship for 2+ years. Last week I asked him about his porn consumption and he told me that of course he watches them. I asked him to explain why, and he told me that even if I am the perfect women for him (no problems in the bedroom, regular sex life, "hot body" etc) every thew days he becomes bored of my body and wants to masturbate to another woman. I have no problem with him masturbating, I can even live with the fact that he intends to see other women than me but knowing that I am not enough for his needs hurts very bad.   

Maybe there is anyone here who can explain a little bit better why it has to be a different woman for masturbation than for the sex? It hurts to know that I can't please him completely but in his eyes I do 100% and everything perfect. In his eyes I do not fail and am "enough". Anyone here who can brainwash me to think not only in my objective perspective that everything is alright but also in my thoughts?

Summarize the given text in a few sentences.
<bot>: I feel unwanted and no longer in demand because my BF says he needs other women than me for masturbation, anyone who can change my mind?
