LOL Yes! I have tried that "method." I've done it a lot, and sometimes it was pretty stimulating and other times, I would just get bored laying there. Lol.
However, besides the water method, there's also hands-free toys. My personal favorites are the strap-on clitoral vibrators, although it's hard to find ones that really fit my anatomy properly. My favorite one is the Jenna's Devilish Fantasies Sting Ray vibe. These are really cheap and a great way for hands-free play. Some are even waterproof.
And my top favorite is Noa. It's designed for being used during intercourse, but for people like me, that's not necessary and slightly uncomfortable, so I just stick it in and let the other portion rest on my clitoris under my jeans sometimes! Loads of fun. I even wore it in public once. On Thanksgiving, actually. I'd been playing with it in the car on our way to a Thanksgiving get-together, which was a long drive away. We had to stop at a gas station, so I just left it in there! LOL. Went inside and everything. It was a lot of fun.
Anyways, besides toys though, you can also use one of those de-tachable shower heads. I have one of those and if you like water stimulation or don't have a toy, they can be the next best thing! You can just move around with the shower head and hold it wherever you please. Even recruit your lover if you wanted.
Hey. This would be a great article topic for SexIs, now that I think of it. You should consider submitting it on the forums on the next SexIs topics!!! I could see that being a winning topic. Couldn't hurt to try. Plus, it'd be lots of fun to write about too.
