I am only 20 years old, i should be at the best penis health of my life, but i find that i am having several problems. For 1, my penis limps drastically to the right side; when erect it the skin is not very tight, but a little loose, and it seems like my penis has got a little shorter over the past 2 years or so. I can get erect very easily, sometimes just sexual thoughts, and i also have ejaculate prematurly (about a minute and half when masterbating). What can i do?
