Anal bleaching is one option. You can also try skin creams that even out skin complexions. But the skin creams option takes months to years to show up, and you have to be consistent with using it. You can't stop and start over or forget to apply it. You have to wash every day and apply the product. Also, you can try drinking lots of water along with using the skin fade creams. You can also try using body oils, rather than ointments or lotions that clog the skin pores. Sweat stains darken the skin also, so you might want to apply powder to areas of your body where you tend to become moist or sweat a lot. Just a few options. Make sure if you get penetrated or play with dildos, that you use a significant amount of lubrication because the constant rubbing of that area can cause the skin to darken also. The reason I know that is because, I made the mistake of washing my face too hard trying to wash off my oily skin ( i have complexed skin) and the rough rubbing darkened an area on my temple and forehead–-I had to apply a medicated ointment of hydrocortisone to the area for months before it actually lightened up and STILL TO THIS DAY if I don't apply it or don't wash my face twice a day, the dark area shows back up; it's all about maintaining it. So you might want to ask your physician to prescribe you some cortisone ointment? Hydrocortisone is like a skin steroid, anti-itch and anti-fungal product with works with different skin issues. There is also Cosmetic Surgery as an option? Just seek the advice of a medical professional in whatever you do, because your skin is the only skin you get!
