I have the AB Silicone silicone thing that attaches to the end of your dick and has a hook for you to hang small weight from it. It's ok, but it's hard to get on and is rather tight. Also, I would not recommend ordering for ABS as they take forever and I think they forget about your order unless they remind you. It was a month and a half before they even shipped mine, and they only did after I threatened to badmouth them on all the forums... Which I am doing now LOL.
