I 2nd that advice!! why limit yourself to only contact with other areas of her body when some simple testing FOR BOTH OF YOU can tell you if you have to even be concerned about anything?
Sex and love are beautiful things. You can't experience the ultimate beauty and pleasure of either if you are constantly worried about "catching something".

Why not both get tested for std's and then you can both enjoy a full and carefree relationship with each other without any residual fear of std's. I bet she would think you caring and responsible if you suggest testing before any physical relationship begins and it will give you both piece of mind.
