Saliva and Mouth

I recently had an encounter with a stripper.  She used her saliva to give me a hand job.  I know that saliva does not give you anything, but she used her mouth to lubercate my penis.  I didnt realize what she was doing because I did not expect her to do that.  She put her mouth on the tip of the penis, not on the whole head of the penis, but half way.  Honestly all I felt was wetness from her saliva.  The only thing that might of can in contact with my penis was her lips.  She did not suck it at all and it was only for one second or less. Should I worry about this?  Is it possible to get an STD or HIV from this?
