After doing pe for about 7 months, i've gained .25 in girth. I started to worry about my veins form the constant jelqing and squezes. They were always prominant, but after pe they got huge. Which i thought was awesome. How can't you like the vascular look? But, I started to notice less firmness and less time I could remain erect. This lead me to investigate. I came across something called horse chestnut. It strengthens the walls of your veins. With the extreme pressure pe creates, I see a total use for this. I bought some and took a week off from girth. I noticed my erections got better. Don't know if it was form horse chestnut or an increase in libido. Just though i'd mention hosre chestnut to the pe community. Any thoughts?
