"Regrets, I've had a few l, but then again..." Well, unfortunately for the next twenty people you are about to meet some have had their regret quotient multiplied by 2. Their initial "mistake" was doing the deed with someone they now have serious second thoughts about and the other was documenting it with a selfie that will keep the regretful memory alive in virtual perpetuity for as long as the web decides.
So have a look. Have a laugh. And then have it be a lesson to you not to have sex while drunk and never take an after sex selfie!
