too much pleasure ??

i masturbate frequently using an electric toothbrush and its truly the best feeling ever but is it possible for the pleasure from clit stimulation to become too much to handle ?? only, ive masturbated so many times and had sex multiple times but still haven’t orgasmed yet. i really want to have the satisfaction of climaxing but it seems i have to pull away before the pleasure literally knocks me out hahhaha.

so shall i be persistent and keep it on my clit or try something new ?
