If you are in love with your girlfriend then it's good that you didn't cheat on her. That is if you believe that she is the one. I remember when I was in college I had chances to cheat and b/c I was in a committed relationship I never cheated. Well the relationships never worked out and I always wondered what if? Sometimes you need to sow your wild oats others a good girl is hard to find. Besides what if you caught something from the bar chick and gave it to your girl? Big trouble then. Condoms don't stop everything.
