when i first started masturbating i remember the orgasms being stronger. they weren’t mind blowing or anything but they were pretty strong and lasted for around ten seconds maybe. but now whenever i masturbate it’s always the same, i rub my clit hard and fast and after a few minutes i cum but it only lasts for two seconds at most and the buildup feels better than the actual release. it’s been like this for at least a year or two and i don’t know how to make them stronger? i’ve tried kegels but they haven’t been making a difference. i’ve also tried a vibrator and it’s still the same. any advice on how to make them stronger or last any longer?
