EWW!! Didnt reall think much of this until now?

when me and my bf had a break, my "friend" tries to steal him away from me, behind my back of course. While kissing other guys to make it less believeable when i heard about it. SLLUTT. Anyways he did endup kissing her and she slept in his bed once. Well the tramp has ! We got back together after all this. I slept in that bed, and kissed the lips she did. Will i contract it?
