petitfaun gave you the most important answer: “…that is one of life’s great imponderables, as it depends on several factors.” It is true, there are many factors that have an impact on the erection angle. If this is your concern, remember that you can stretch in all directions. Most guys think that by hanging weights your erection will not be as high or as straight forward as it used to be. Well in some cases, telling from some hangers’ experience, the hanging affected very little the erection angle. But you also have the option of stretching upwards. If one direction should not get your dick down, that is when you stretch upwards.
