Transmission in the scenario you described is Extremely unlikely.
That being said, something like 80%-90% of people have the herpes simplex virus. For the overwhelming majority of people the symptoms are so mild they don't even suspect they are infected. Herpes has an undeserved stigma. So, It can cause little red bumps every now and then. People are always covered in little red bumps; for instance, pimples, bug bites, welts, scrapes, whatever. There should be no shame having herpes, so few of us do not; the uninfected are the weird ones.
Your complaint may be a pimple, or a boil, or a bug bite. Herpes bumps are usually star shaped I believe.
If it is painful enough to have an impact on your day then perhaps you should see your primary care doctor.
I hope I alleviated some of your concern over getting herpes. In closing, I'll remind you that I find it extremely unlikely that you contracted herpes and are experiencing an outbreak based upon your sexual history and description of your condition.
