1. Mom caught me masturbating. Also (different time) Mom caught me looking at porn on the computer. Mom caught 19-year old me and girlfriend in bed together (a big no-no for my family) by walking in WITHOUT knocking (also a big no-no).
2. This one's disgusting. You're warned. At a party, I was feeling frisky and stick my hand down same girlfriend's pants to grab her ass and I feel liquid. My hand was covered in you-know-what (NOT urine). I ran upstairs to use the bathroom and SOMEONE'S IN IT! I had to wait for 5 minutes, holding my soaked smelly hand (at least 3 fingers drenched) waiting for the lousy bathroom. Couldn't have scrubbed enough. At least she apologized later when she sobered up.
3. Falling off the bed too many times to remember. Broke a futon once.
4. Having sex with the GF bent over in the shower of a motel six and grabbed for the shower rod and it and the drapes came down hard on the girlfriend.
