Base Ring Design

I spent roughly a week in my Chinese Jailbird model, went out for the day, and then put it back on last night. The nighttime erections felt stronger after that single outing. When I woke up at 5:00 A.M., I got up to urinate and let things calm down. Usually, if I return to bed too quickly before being completely soft, they firm up stubbornly again. Lying on my side with my legs slightly apart, I held the erection behind the ring and gave it a gentle massage. I noticed something inside—a vein or perhaps a ligament, though I’m not certain—running along the underside of the shaft. It makes me wonder if that’s what gets pinched so painfully during an erection. I haven’t seen any rings with a notch or dip at the 6 o’clock position to relieve pressure there. It seems like it could help significantly. Does anyone else have thoughts on this?
