I have a "tradition" that started in my college days. Around Halloween time, whenever my school is hosting the main celebrations for the day, I become the g-string alien and roam the school! Yes that, one alien mask, one g-string, shoes for good measure, and nothing else! I narrowly escape getting in trouble every time, but it's worth it.

I believe the most embarrassing thing that happened to me in my recent live was a few years ago, when I got too drunk at a new year's party. There was like, just four of us. I got invited there by a girl I was crushing on at the time. Needless to say, now we don't talk anymore. The one good thing I got out of it is knowledge of my alcohol threshold.

I don't have a lot of physical fears. (Though I'll admit horror movies work way too well on me...) My fears are more on the existential scale. Stuff like, fear of being rejected, forgotten. Being alone all my life.

My greatest turn-on is empathy! If I feel the other party is interested in me, that's a big boost.
My biggest turn-off is lack of self confidence. Saying you're unattractive contributes to your unattractiveness more than your actual physique if you ask me.
