I am not surewhere to put this, but I hope this is the right place. I went cycling or a few days. I noticed that while cycling my bloodstream in the penis gets a little blocked. I get this numb feeling sometimes in my dick. But when I come off my bike the blood starts flowing and I noticed there goes al lot of blood down there. As if my body wants to really make up for the lack of blood my dick got while cycling. And although not aroused or anything, I get a semi hard one. Does any one else have experienced this?
