Dear friend ...
Thanks for your query to Healthcare Magic ..
I read your concern and there is nothing to worried as it is just a various health problem and it is not associated with unprotected sexual intercourse . Do not be panic , I would say that rashes on thigh doesnot mean that you are suffering from HPV
/ STDs ... You are perfectly normal , Its due to allergic reaction
in your body made you concern ...
Steam inhalation and antibiotics will cure your symptoms .
Do not be worried , and use protective measures in future and have a good hygiene , Wash genital region with warm water and use medicated soap to prevent furthur itching in thigh region .
Keep the area dry and clean.
Ask me furthur if you have anymore queries ..
