Hard and semihard for over 3 hours today

I've been taking pictures, posting pictures, and scrolling pictures for and on LPSG for over 3 hours now, and I've been hard or had at least a partial erection for over three hours now. My cock and balls ache. I've been on the edge of cumming so many time, but I won't let myself blow my wad. It's been about a week since I last masturbated or cummed. Damn, I need some fucking relief! I've seen those erection commercials about seeing a doctor for an erection lasting more than four hours. I better log off and try take think about something else so I can go limp and don't injure some vital organs--the cock and balls. Here's a shot of what it would look like if you were down on your knees helping a guy out.
