I wanted to report on wearing the short tube. It is workimg out very well. After I had researched it, my Master commanded I get it. It was locked on Monday afternoon. I don't know if "more comfortable" is the word, but certainly more satisfying.Where the cock could get flaccid and not fill the tube, that's not a problem witht he short tube. Master likes that I am always "full tube".
It's not a problem to wear, though any erections are obviously more intense. The nocturnal erections are intense, even painful. One tip on that is to get up and pee. That will relieve it, though the first night I kept getting erections.
One tip is to lube with A and D oint. Using lube that stays lube helps longterm wearing. Triple antibiotic may also work, and should theoretically help with hygiene. I'll try that next time I'm released, and report on that
So, in conclusion, assuming your anatomy is appropiate, the short tube is very satisfying for Master and slave.
