While you can get genital hsv1 from receiving oral sex, what you are describing doesn't sound at all like it.
It sounds like pimples or infected hair follicles. Your doctor doesn't think it's herpes, either.
If you are going to engage in unprotected oral sex, you should know that you can get gonorrhea, chlamydia, syphilis and genital hsv1 from receiving oral sex. If you are giving oral, you can get oral gonorrhea, chlamydia, syphilis and possibly oral hsv2.
Oral sex is much lower risk than vaginal or anal, but there is still risk. Giving oral to someone with a vaginal is lower risk than receiving oral. Giving oral to someone with a penis is higher risk than to someone with a vagina, but still not incredibly high risk.
If you want to test, you'll need both genital and oral testing.
I wouldn't freak out - oral sex is lower risk than vaginal and anal sex.
