Have you consulted with a dermatologist or your doctor? There is the option of cosmetic surgery if it is really bothering you. It might not get rid of the scar one hundred percent but would help. Vitamin E would likely be safe to put on it and that is known to help with scaring. The penis is so sensitive that you want to be careful with topicals. For me, I don't know if you are single or something and think anyone is judging you for having a scar on your penis, but really, would think not. Women likely really do not care. And it's not on display. I'm not trying to minimize your feelings. But I'm sure I'm not alone when I say that I don't care about a scar on my partner's genitals.
