Every time I have sex with my boyfriend he cums so quickly like maybe in one minute which is annoying because i want it to last longer. He used to last a long longer before especially if we did it more than once in a day but now every single time he cums really quickly. Idk if he cares or not but he does try to continue sometimes after he cums and I think maybe he tries to hide that he cums bc sometimes I don’t even realise it bc he doesn’t say anything and just keeps going (but can’t continue for too long). What can we do about this
