The four balloon and pillow method. Fill four balloons full of warm water, wrap them ina pillow, and go to town. Like a cheap, fake, poorly made vagina. Slightly melted wax.
I've heard that if you get a lubed up plastic bag, put it in between your bed and the matress and fuck like a bunny rabbit, it's supposed to be effective ...
Personally, there's nothing comparative to sex. Masterbating feels good but sex feels 100 times better. One of my ex girlfriends bought me a pocket pussy for me right before I went out to sea for 3 months (I was in the US Navy for four years). It was nice of her to do that for me. I think she just didn't want me to cheat on her while I was gone, too bad she decided to cheat on me instead. Anyway, The pocket pussy is great for acouple of reasons. It feels almost like the real thing, it's ribbed inside and squishy, and it's easy to conceal and clean. I would take it in the shower with me and it would be so nice.....
I've heard and tried this one, Fill a condom with water while your in the shower and then put it on. Hold on to the condom like it was your lover and start humping it. It doesn't work well at all. I didn't feel anything except warm water, I need that little bit of friction to get my jollies off....
tried it...it feels good sometimes but your bed has the be the exact right height, you have to lean on the matress to ger enough pressure but you can't put all your upper body weight on it or theres too much pressure so its a bitch to stay in teh right position, your knees chafe a lot on the ground, the bag dries out eventaully and all and all, its nice at first but you'll prolly have a real hard time cumming. not worht the effort imo
I find the best way is through the use of Peanut Butter and a sandwhich bag it is kind of complicated so look at the site in my signature for more details... don't knock it till you've tried it
