husband has what is believed to be an irritation.  right at the base of head of the penis it is red and he complains that it burns from time to time and has just a little itch to it.  he has tried neosporin which he said relieves his pain.  would it be wise to give anitbiotic such as keflex?
HelloThanks for query. The burning sensation at the tip of the penis that your husband has is due to inflammation of terminal part of Urethra due to unprotected sex. This could be secondary to your vaginal secretions which are acidic in nature. Please get yourself checked by a qualified Gynecologist and take necessary treatment. He needs to take broad spectrum antibiotic like Lifetime along with anti-inflammatory Chat Doctor. Along with topical antibiotic ointment like Newsprint twice daily. Ensure both of you wash your genitals with warm water twice daily. Ensure to avoid sexual encounters till it heals up completely.
