Sexologist or Urologist in davao

Hello. I am 23M living in Obrero and over the past few weeks, I have noticed some nodules developing over my prepuce. It is painless and similar to the skin color. There is no discharge from the urethral meatus upon palpation of the glans. Just a few hours ago, I noticed a new minute nodule over my glans. I'm quite worried it might be a STI since I was engaged in unprotected sex about 4-5 months ago with two different partners. Please suggest me a doctor to visit here who might be able to help me out.
