>:( I have been using a standard STJ that I bought from KMart. I use warm water and pump my balls for hours and I get zero results other than a nice pain from the edges of the jar. What am I doing wrong? When I use a pump for my penis, that always works really well.<br><br>Thanks.

I'd say get some sort of rubber seal.  

i agree, make sure the seal is air tight, turn the tube up and have all the water facing u, if u get any air bubbles u dont have a good seal, which will lead to your your problem

I used to use a STJ, but it started to CRACK one day and ive been turned off by using anything glass. Luckily, I found a plastic container at either Target or Walmart, and I use the rubber STJ seal you can buy separately. In addition, i use a 1 dollar one-way valve I got at Petsmart, and I use my mouth to suck air out. <br>As far as results, I also had slow but progressively larger results. I can now pump for about 2 hours and get about 12 inches in girth on my balls.... If you want a pic of my contraption, let me know your email and ill send you the pic.

My advice is to soak your scrotum in -very- warm water first, think "hot-tub" warm.  Pumping with warm water in the jar and/or a heating pad is also a really great idea.  Lastly, you should seriously consider getting the STJ seal from pumptoys.com   And no, I still don't get any money from them for recommending it, I just love mine enough that I think other guys would love it too <br><br>Cheers

i agree with mruss, thats the way to go.....<br>
