No interest in sex

Can too much sex make you lose interest? My boyfriend has a high sex drive and I think because I’m on birth control it’s fucking with my sex drive I have zero desire anytime. Most the time I just give in to get it over w and make him happy. He doesn’t care if I don’t want to cause he can go with out but I don’t wanna be a bummer. It’s good sex just I’m not interested in it and never have been. Not to mention I bleed everytime we fuck cause he bangs my cervix :/
