Pics or it didn't happen.
Well Ladios, you're 18. You're young. We're all young really (except Bisjac), and these kinds of relationships don't usually last. Unless this girl who you say "loves" you is really the girl you plan spending the rest of your life with, then I say you should have kissed the cheerleader. I mean, you still have a lot of life left to live. Hell I'm two years your junior, so I have even more life to live, but I don't consider any relationship I have at this point to be permanent. Because frankly, there's still a lot left to see.
Also, stick it in her pooper.
