What nudist to be ruled out
Damage to the lower spine/sacrum
High blood pressure.
Circulation problem in the penis [need ultrasound, which can be done in a urologists office].
All of these need to be considered.
There is no proven reflect of the products you mention.
Please see this web MD article about substances which have some evidence for helping
However, these will not work like viagra, cialis, or levitra.
