Hi there ~
I understand your concerns. I am glad you are seeking help on this forum. I believe that the description of the lesion fits
into the diagnosis of molluscum contagiosum
or genital warts. Having poor genital hygiene is one of the many causes of the disorder although having had oral sex
in the past may have contributed to it as well. The solution is to have it examined by a dermatologist
and getting medication to help cure the infection as it can be done easily. I hope this helps relieve your anxiety
Take care and have a lovely day!
