The high hair line and turkey neck don't really cause erection problems. They're just a sign of a tight cut. Like you said, it's just cosmetic. Before I started doing FR, I was having problems with erections, too. In my case, it was mainly due to loss of sensitivity. I have noted that, even without full coverage, just getting enough skin to be "loose cut" has remedied most of my sensitivity problems. A large percentage of the sexual nerves of the penis are not touch sensitive nerves but stretch receptors. They fire off when the skin is pulled and tugged, not stroked, which may be why restorers who were tight cut report a much greater degree of increased pleasure than restorers who are loose cut. After getting some slack, their once drum tight skin is slack and mobile and those stretch receptor nerves are finally being put to use and firing off. Stress and diet do have an effect on erection quality and sexual satisfaction, but not as much as sensitivity. A rough day at the office isn't going to keep you from getting hard if it feels so damn good! In fact, good sex is the world's best cure for a rough day at the office.
