When I am doing the basic stretches it seems that I am putting a lot of pressure on the head of my penis, regardless of whether or not I grab right below it. I was reading in a post earlier today about some Andro device, that has a noose, and in that same post someone mentioned something about a nerve that runs up the middle of your penis and if you apply too much pressure to it, you can basically say goodbye to erections in the future. I've watched the videos DLD has in the paysite and it seems that I am doing everything correct but the fear of losing the ability of an erection scares me. Could it be possible to squeeze too hard right below the head when stretching, because in order for me to feel a good pull I seem to have to squeeze pretty hard. I'd really appreciate any help. Thanks
