feeling so unwanted...

my bf and i have been together for a while. i love him a lot amd hes very sweet, but i feel so taken for granted. ill flirt with him and try to be sexy for him but he's almost always focused on something else. we take showers together and we usually get very flirty in there, but whenever i ask if he wants to shower with me he doesnt sound excited. he tells me hes always attracted to me and he's always excited to take showers together or have sex, but he doesnt show it. its been months and im reaching my limit
