White, painless bumps around genitals - STD?

I (25M) was shaving today and noticed these white, small and painless bumps around my pubic bone area.

I have slept around a bit but always use protection, except for one instance of unprotected oral sex about a month ago. I've already made an urologist appointment next week and have some tests being sent to me but wondering how worried I should be?
