I do not have your answer, but I do have some ideas for you. Certainly your experience at 22 is not the norm and needs further investigation. I think that you need further evaluation and I would approach it from the physical and emotional aspects at the same time. Whatever is physically happening has emotional consequences and may make things worse if not addressed. Find a urologist who has a particular interest in sexual dysfunction (you can check on www.sexualhealthmatters.org for a clinician in your area, though the list is not currently up to date) and also find a sex therapist (either via google or through the local psycological association). If you find one, they will know of the other.
As regards your penile indentation, all peyronies does not have a plaque. There may only be a scar contracture that angle the shaft.
Good luck!

Boston Medical Group medicine works for me every time. None of the pills ever worked for me either. You can look them up online. Good luck.
