You won't get it from a peck on the cheek - the skin there is too thick to penetrate.
If it was a cold sore on her lip, you could get genital herpes from the oral sex - it would be genital herpes type 1. The condom you used would reduce the risk significantly.
Do you know if you have oral herpes type 1? Have you ever had a cold sore? Even if you haven't, you can still have it. About 50% of the adult population has it orally, and about 90% of those will never have a cold sore. If you have it already, you can't get it again.
Licking your scrotum won't transmit it. It's direct contact with the lips that would transmit it.
