Hi,

With your history, yes it is probably Tenia cruris infection (fungal). It responds well to antifungal creams. However for complete cure and to avoid recurrent it needs to be used for at least couple of weeks twice a day.

After bath always apply antifungal dusting powder available with the chemist and also smear some powder to your under clothes.

In addition:
Keep good hygeine.
Never share towels etc
Never use wet underclothes.
All underclothes should be steamed well before using them, though they are well washed.

It is important to rule out similar infection in your wife / sexual partner

Hope your query is answered with your satisfaction. Please feel free to for further clarification.

Thanks
