PLEASE HELP ME!!

okay so cutting straight to the point , I’ve been with my boyfriend for a year and a half, I used to be turned on all the time but for the past 5-6 months I haven’t been getting aroused and I never want sex anymore, I have got yeast infections a few times but I’ve used the cream to get rid of it and I’m on birth control (pill diabetes) but I went off it for a few months to see if my libido would increase but it didn’t .. please help me out I don’t want him to always feel disappointed in me ...
