Unfortunately there is NO CURE for what you have. From now on and for the rest of your life, you will have to tell any sexual partner of this condition. If you do not, you can be sued as a "sexual predator". When the "anus" is infected, warm baths will help. You can also apply an "ointment" which will reduce the "itching". For your "mouth", there are over the counter medications, ask the Pharmacist. You have probably infected yourself at a time when you had a "cold sore" and you were not careful when using the "washroom". You have transferred this virus from your mouth to your "bum". You are highly contagious and therefore you should NOT share anything in the washroom with ANYONE. You use your Own soap,face cloth,towel and WASH YOUR HANDS FREQUENTLY. Take my advice, as I know what I am talking about. Good Luck and live a clean life, and remember what I told you. Do not kiss anyone when you have a cold sore either. You are Highly Contagious.
