I hate to burst your bubble, Jack, but your sweet 18 year old girlfriend is anything but *innocent*. Being her mother's best friend, I happen to know of at least four men with whom she has... copulated. Men, Jack, not high school 'boys' like yourself. I overheard two of them discussing her 'cunt' in some graphic detail. Apparently she is a screamer and a squirter.  Oh, and she swallows.

I'm not saying that you shouldn't date her, just that you probably should get over your whole 'saving it til' marriage' attitude if you want to stay with her...
