update on boring sex life

so after a couple comments telling me I should be open with my boyfriend and tell him i’m not satisfied with our sex and I wanted more he got so defensive and said “ well we just won’t have sex at all then “ then he proceeds to say “if u want to fuck somebody else go head “ and we are no longer together after this . I don’t understand how me telling him my needs in our relationship made him so mad to the point of us not even being together anymore 🙄
