Okay, so everyone’s different, body responds different ways, yada yada yada…
But on the whole get edging four or five times a day, and doing it hard last thing at night and first thing in the morning will get you there, in perhaps a week. Fucking with a dildo will get you wetter than just clit stim, and keeping your pussy teased with something like a crotch rope or even better, ben wa balls will often, literally, have you dripping down your thighs.
You don’t have to start over if you cum, no. But you’ll be much hornier and want to edge more if you don’t. Plus I don’t want you to, so no cumming. Not until you can squeeze your cunt and watch a drip of your arousal fall to the floor.
Oh yes, and if this is your thing, wax or shave everywhere below your mound, it’ll feel so much more intense and keep you much more aware of it as your pussy lips slide over each other every time you move.
Finally, wetness varies a lot during the month, so just be aware of when your period is and figure out how your body reacts over the whole cycle.
