I had this very recently and it was an awful shock.
Had to make a very embarrassing visit to our family doctor & denied any sexual activity when asked (I am single but she knows my family very well over the years).
Urine tests, blood tests and a prostate examination all followed, to my further embarrassment.
I was told I probably had an STD but, since I lied and denied any sexual activity, I was treated for a UTI.
Everything has now cleared up & all tests were 'normal' but it was rather concerning.
Now referred to a urologist but mainly due to my age - informed there is nothing to worry about.
I hope that helps you and, if you need additional info, please PM me, so long as it's not personal, I will try to help.
