As you know, I can't try to make a specific diagnosis online, or to give definite answers; those will have to come from your own healthcare providers. All I can do is discuss probabilities.
Those probabilities tell me you probably don't have genital herpes. First, if the right kind of blood test was done (e.g., the HerpeSepect test; see numerous other threads on this forum about herpes testing), the results are highly reliable. I don't know what sort of "cold sore" you had as a child, but perhaps it wasn't herpes; it it was, your HSV-1 test should have been positive. More important, the negative HSV-2 blood test result is a strong indicator you don't have that virus. Second, the infection you describe in the shaving area sounds just like folliculitis, not so much like herpes. Third, the exposure(s) you describe with the partner with genital herpes were very unlikely to result in HSV transmission.
The information about oral HSV-2 infection is confusing. Initial oral infections with HSV-2 aren't all that rare; a fair proportion of persons who have initial genital herpes also have oral lesions. It also just "makes sense" that either HSV-1 or -2 can infect any exposed site. However, for reasons that are not well understood, recurrent oral herpes due to HSV-2 is very rare. Almost nobody with recurrent oral herpes has HSV-2.
Of course, there is always the possibility that your blood test was inaccurate; wierd things happen (e.g., if the lab somehow mishandled the specimen), or perhaps the lab wasn't using up-to-date testing methods. So you might have the test repeated. If you do, make sure your provider orders a truly type-specific blood test such as HerpeSelect. You can also be on the lookout for more "outbreaks" and arrange to see your provider immediately (same day) for a virus culture.
I hope this helps. Best wishes-- HHH, MD
A related discussion,
oral sex and HSV 2 was started.
A related discussion,
Non-sexual contact after lesion was started.
Most STDs can at least occasionally be transmitted by oral sex; most are much less efficient by cunnilingus than fellatio. HSV-1 very readily, HSV-2 less so. HIV transmission is rare by fellatio, primarily from penis to oral partner, almost nonexistent in the other direction; and to my knowledge HIV has never been transmitted in either direction by cunnilingus. Syphilis yes, gonorrhea yes. Chlamydia is transmitted orally rarely, if ever, in either direction. HPV probably can be transmitted, but rarely causes disease or persistent infection of the mouth (and probably is not transmitted mouth to genitals). Ureaplasma is a normal bacteria in almost everyone's genital area, not a cause of STD, and to my knowledge oral transmission has never been studied. Finally, as discussed many times on this forum, it is likely that bacteria that are normal in the mouth and throat sometimes cause inflammation (nongonococcal urethritis, NGU) when transmitted to the urethra during fellatio. No similar problem has been reported for cunnilingus.

Can you once again clarify what can be transmitted through unprotected oral sex(receiving)?
Can ureaplasma?
Many thanks for your answer and the reassurance. I will book an appt. just to be safe.
yes, I would be interested as well in receiving clarification regarding what can be transmitted via oral sex, thanks.
