Oral herpes is a off topic for this forum, since it's not an STD, with rare exceptions. Half the population has it, usually acquired in childhood. So you could have it. If you do, it isn't causing the symptoms you report. Also, you are asking the most basic, simplistic questions about herpes. You need to read about it. See the informaton on herpes at www.cdc.gov/STD or www.metrokc.gov/health/apu/std. Until then, some brief replies:
1) Once a herpes lesion starts, it lasts at least a week until healing, usually 10-14 days. Therefore, the bumps you describe cannot be herpes.
2) Adults who don't already have oral HSV-1 usually get it by kissing an infected person.
3) Regardless of question 2, of course you can get oral herpes if you have no genital herpes.
4) HSV cannot be cured, but medicines help control the symptoms.
5) Read the information at the sites I suggest.
Oral herpes without symptoms rarely is an important health problem. I suggest you forget about it.
