Don't be ashamed. I keep a vibrator in my purse for this very reason. Sorting yourself out is the best way to cope. It's not dirty or bad. In fact, it's almost normal (if you're male). Societal standards suck; don't let it make what you are going through make you feel even worse. That seems unfair. I look at it this way: at least I can sort myself out and haven't thrown myself at any strangers even though I have thought about it.
