White type of bump on my Penis near frenulum

My only sexual relationship was with a call girl, in November of last year. After that I noticed a white bump near my frenulum (maybe had it before but never seen it) Negative for Syphilis, Chlamydia, Herpes, HIV, Hepatitis... I went to a urologist and he said it's normal, but is it really? I'm afraid it's HPV.
