There are techniques to stop it from happening but I find I enjoy it so much, I just go with it. So these days, it practically happens every time I orgasm… and doesn’t even require that. I’ve squirted in my PJs just from my husband licking my ear and whispering filthy shit into it, and sometimes just a touch to my clit or my opening when I’m really aroused produces a spray. My husband and I developed a number of fun little techniques that will usually generate a quick spray if you’re ever interested.
Most important thing to have it happen again is just to relax. You CANNOT push, ie bear down or else you’re likely to kill it.
What did the trick the first few times for me was edging for like 40 minutes and then finally letting myself cum. At that point, I was so wound up, my mind was entirely focused on how good I felt and not on how much I wanted to squirt.
Also, I’d suggest buying some leakproof blankets so that you’re not worrying about making a mess of the bed (just you and your BF!). These haven’t failed us yet.
The guy who wrote the Bible on cunnilingus (She Comes First) also wrote this: https://www.amazon.com/Passionista-Empowered-Womans-Pleasuring-Kerner/dp/0060834390
I highly recommend reading it on your Kindle or computer or whatever. Seems like a stupid book couldn't help you but if I could I'd bet you money that it will be useful to you!
Its been trucking for a year! Lots of options, plenty of power.
