I'm sure i've done tons of oppsies, but the only one that comes to mind is:

One night when i was maybe 13 or 14, I was in my PJ's and i went to my step sisters room to get somethin, and she was in there with her friend, and they started laughing at me, I found it odd but just grabbed what i went there for then went to my room. Then when I was just aboyut to go to bed, I looked down to see my penis hanging out of my PJ bottoms! OMFG was I so embaressed...
