Ok, so I may start a thread about this later, we'll see.
I haven't done much PE since the 'shock routine' 10 days ago, some light pulls in the bathroom.
Yet despite this lack of activity, I've got something somewhat worrying going on down there from edging!
Earlier on today I had what's probably my longest edging session to date (I've had some good progress regarding involuntary kegels so I made a point of it). So somewhere around 1&1/4- 1&1/2 hours. And since then my flaccid has been worrying swollen, for a while I thought it was the dreaded 'hard flaccid', but I'm actually hanging quite well. That may still be possible with HF, but I tend to stay out of those threads so I'm not sure.
I immediately showered and heated the area for 20+ minutes and was doing helicopter shakes at intervals etc. And I've kept warm since. No change upto now really.
Basically the top half of my shaft is swollen. I'm hopeful it's just the skin behind the glans, and possibly some of the foreskin. May post some pictures but I'm not sure it would do any good to be honest.
Edit: I just worked up an erection out of curiosity to see what it would be like, the swelling remained but I'm pretty sure it's just in the skin. Could be the 'donut effect'.
It could also be 'temp gains', something I've never experienced before, but then it wasn't noticeable while I was edging.
I've done a little bit of research and found 'swelling after masturbation' a few place. Should also add that while I was erect it was a bit uncomfortable at times.
