I been experimenting and just wonder why I don't cum. I have a Tims device and its pretty strong and have had it up to full power and although it does get my cock very hard I've only precummed during the process. Should I expect I just won't cum ever from this, I've lasted up to an hour already. I've experiment with everything except anal probs which scare me. I usually use a cock and scrotum metal ring with the second one somewhere on my cock I usually move it to just under the head where it seems to get me the hardest. I even used a edge tube and pump while estiming and almost got my dick stuck in the tube of the pump. That sure was a test on my endurance threshold. Any ideas on me achieving orgasm?
