Dear Welcome to HCM We understand your concerns The red ring around your foreskin may be dryness and hygeine related. It definitely will be sore an sometimes itching. Hygeine conditions ar very much essential for genital area. Wash that area with warm water and mild soap at least thrice daily. Use some lotion like lacto calamine which might help. Use light and thoroughly rinsed undrgarments. As you did not mention about unsafe sex, you don t have to worry. Do the above for three days and if there is no difference, then consult a dermatologist. Wish you easy recovery.
