So I literally just figured this out and felt the need to run on here and share.
"markwashere" ; - That technique is what really helped me! And the "squishy walnut" description - lol! So true!
How I did it - I masturbated manually for quite a while. Position-wise, I read somewhere on here that having one's butt in the air helps a lot. I take one of those pillows with the arms that sits up so you can read in bed and flip it over to make a wedge, put my butt on the higher end, and lay down with my head on a pillow lower than my butt.
I'm pretty new to all this and this was my first solid attempt at masturbation with just my hands. It took 45 minutes to build up and find the way my G spot likes to be handled. What worked for me was a bunch of clit rubbing and finger thrusting to warm up. Then I took my middle finger, inserted it, and tilted it up until I could feel the squishy walnut. Kept stroking it and playing with it until I could feel the urge to pee, then I just kept stroking and stayed relaxed until it let go. I left my finger inside and kept stroking during the squirting and it kept going for a while. It feels pretty great and is all warm.
For me it's more of a "gush", I imagine if you were to tighten muscles down there or did it in combination with an orgasm it would be more prone to "squirting" or "projecting" . I prefer the gushing because it's a bit easier to control and clean up. But dang, I must have put down 5 towels and it went right through all of them...then again I did feel the need to try it again...and again...for a total of 3 on my first go...
Looks like I need one of those purple blanket things...
Thanks for all that advice up there you guys!!!
