Bleeding Gums

Recently I made out with a girl, we never had sex or did anything of that nature, just making out. Shortly after that my gums began to bleed. Later I noticed that when I made out with my girlfriend her gums started bleeding shortly after. I know that the girl I made out with had been active with other guys. Why are my gums bleeding? Could she have given me something?

You need to go and be seen.  Thsi doesn't sound like a std but it needs further follow up. Your gf also needs to see her own provider too.
