<human>: While my girlfriend was on a trip (at the time we had been dating for about 2 months), I skyped this girl I had met around March from across the world. Never met the girl, never want to, but we chatted occasionally. Well, I fucked up. She asked to see my nether regions and I complied, doing nothing sexual, just dropping the britches for a brief second. Now, directly after, I deleted her, blocked her, and felt so FUCKING guilty, to a point i wanted to just bend over and die. I'm not the kind of guy who would ever consider cheating on my girlfriend, because truly, she is my first love. But, I don't know how to break this out to her without screwing us up. I fucked up, I know it, and it hurts me to no measurable extent thinking about how I may have hurt her. It was the biggest mistake I can ever think of and will never again do something so completely stupid and thoughtless. How do i go about telling her about it? Honesty is so important to both of us, but I'm so scared. Please help /relationships. ;(
