Low sex drive 😔

I've been having some low libido for the past few weeks and it's been affecting my sex life with my bf. I haven't told him how I feel, but when we have sex I don't feel anything like its not pleasurable. I don't know why I feel this way. I masturbate every 4 or 5 days compared to before when I would do it everyday. I adore my boyfriend and he's always turned me on but I haven't been able to get very wet or turned on lately. Should I talk to my boyfriend about this? I don't know what to do I really want to get crazy horny with my boyfriend lol. Just need some advice.
