Dngnkeeper, your information was great...and very interesting.. As Jadetiger said....there are few things that we know about a submissive male and I think that is a very interesting discussion.

For sure I am interesting on knowing some more details...for the use of cock rings and ball stretchers!

You also wrote: "There is also the area of vacume manuplication where the goal is stretching. This can induce some unique sensations due to the stretching and leaves the penis, especially, ultra sensative".
I would be greatful if you say some more details about that..
