I am new to PE and have been doing it for about a 1 1/2 weeks and I had a very scary moment yesterday. I was doing my jelging session after hot wrapping and stretching and upon finishing, I decided to try out a penis ring I bought to use with my girlfriend (those things really do work well by the way). I put it on and masturbated to see how it feel but I held back my ejaculation for about 30 minutes. When I took it off one side of my dick by the head was swollen. I got nervous and masturbated until I ejaculated thinking that perhaps it was some trapped semen but that didn’t do anything to subside the swelling (told you I was new). Finally after some time of massaging and rest, it went away. Is this normal, is it good, should it be expected, and what could have caused it? Thanks.
