i think im cursed

Everytime me and my man have sex he always cums within 5 minutes or less . It gets me really mad . We always have oral sex before and what not , he sometimes makes me cum when he eats me out but i sometimes dont cum for idk what reason even though his head game is good . Does any one have the same problem ? Idk if he comes fasr because its good or because he wants to get it over with ?! We have been together for 4 years going onto five in august , he would have the same problem but never as fast as this ! I wanna get fucked for at least 20ish minutes because i love the feeling of him inside me lol
