Kissing is not really a risk for any thing, if anything HSV1, mono and or Gono.... but this tooooo low of a risk to worry about. and you already have two out of the three sooo I wouldn't be toooo concerned... and Monos not really an STD.
Agree with kdaily except for the part about gono...this can not be obtained from kissing.
You have no worries from kissing.
