this is very, very low risk. they could've been shedding hsv1 on friday but odds are they weren't. as was already said, just saliva is a poor way to transmit hsv1 and odds are it didn't occur.
if you contracted hsv1 anally, you'd have pain , itching and obvious lesions there.

Sorry to be annoying about this, but are you sure I shouldn't be worrying?
The person had a cold sore 48 hours after I was with them. There was no mouth to body contact at all, but like i said there was a decent amt of saliva used. If I contract hsv-1 anally, how would I know?
Saliva is really not a good means of tranmission for herpes. This isn't much of a risk. If you have symptoms be seen within 24-48hrs for a lesion culture. However, at this point I wouldn't worry.
