i need advice and ideas! my bf literally cums after 30 seconds and idk what to do to make him last longer so sex is more enjoyable for me. i googled a technique called "edging" where you get close to orgasming but you keep stopping to build a tolerance, but he said he tried that in the past and it didnt work. im thinking of trying de-sensitizing condoms/sprays i hope hes open to it. any other ideas?
