well yes you can get herpes at birth from your mother. I am not sure if the symptoms are the same for a baby as an adult. Or if they remain the traditional herpes symptoms.
But you do not have to have sex to get genital herpes or oral herpes.
You can get oral herpes from sharing a cup with someone or even kissing someone with a sore in or on their mouth.
Genital herpes is most always transferred through sexual conatct but there is still a chance to get it from non-sexual contact. Like one day you touched or popped your sore and immediately after you masterbated or used to restroom and transferred the virus to your genitals. The other way is if someone with oral herpes gave you oral sex.
Both these circumstances are very very rare, but possible. The saddest thing about herpes is that its so hard to track down when and who you got it from.
My suggestion for you is to go to a doctor and get a blood test done to check for oral and genital herpes. Until you do that you will remain confused. Also until you find out for sure make sure to use protection if you decide to be active.
do you have anyone you can turn to to get help with testing like your parents? Or maybe an aunt?
