I was a first timer this evening.  However, concerned, even though I may not be.

Evening was "protected" in every way.  However, we engaged got into kissing mouth to mouth and then spontaneously started french.

Should I get tested for anything, STD's?  Will kissing cause anything?

Please advise.

Good question...don't be concerned.  Catching anything mouth-to-mouth is virtually impossible (I think you are probably referring to HIV).  The virus has a short shelf life and doesn't do well going in saliva.

Happy kissing!!
