i had a protected condom sex with a girl, last few weeks i have tingling sensation on the top part of penis. went to see a doctor and he told me i have a yeast infection, i wasn't clear of what that is but there's like fungal white pimple spots behind the top of the head. there's no any white discharges from the tip only tingle sensation no pain when urinating. i'm afraid i got infected with std..i had sleepless nights thinking about it
