Hi. I'm A 35 Y/o Healthy Male. I Have Had

Hi.

I'm a 35 y/o healthy male.

I have had urethritis about two or three times in my life.

A couple of weeks ago I saw a drop of white discharge at the tip of my urethra and suspected urethritis again. This happened without me having had unprotected sex.

I went to the doctor and had a swob test done.

I got the results and I have what seems a mild infection with Staphilococcus Hominis.

He prescribed Doxiciclin.

1. Is this an infection? I read this is a pretty common bacterium present on the skin.

2. Should I treat it?

3. Why do I get urethritis so often? Other than oral sex, I don't have unprotected sex. (I'm hiv neg and don't think my immune system is weak)

Thanks!
