Interesting ejaculation experience.
I was edging close to TPONR for around 30 minutes the other night, after not having ejaculated for a week, and right when I was about to ejaculate, my erection went from a 9.5 or so to over a 10.. the hardest it had ever been in my life. It actually scared me haha. It seemed like it seized up for a good 2 full seconds with me not being able to control it before I came, and came a lot.
Just wanted to share my experience!
