<p>shermani is 100% correct. Lying is the worst way to go. Own up to it, be clear that you have learned from your mistake (I wouldn’t even bother with the “it was my only time” line, even if true it sounds lame), and that you have gotten the urge to experiment that way out of your system. It is hardly like you are the only one that ever got caught drinking or doing drugs in high school. You will come across as much more mature if you take responsibility.</p>
