based on what i have researched the tunica is a coat that is around the corpus carvenosa and the suspensory ligaments are at the base of the penile structure, why is it that when you do normal stretches you are working the suspensory ligaments, and when you stretch up your stretching the tunica more, also when doing stretches close to the base its's for the tunica wouldnt't it be more for the suspensory ligs ?? sorry is its hard to understand lol
