Good luck with your future choices.
We all screw up in one fashion or another. Then as we all know, you just pick yourself up, dust yourself off and go forward. Hopefully, you'll make a few personal changes (with regard to your base desires) along the way.
Not sure if a new girlfriend is going to keep you away from "this". It's an addictive habit you men have!
If you do decide to still hang around, which a few of us are guessing that you might, glad that you're having a change of heart about what is important to you, sexually. You need to change your viewpoints/wants/contents of PM's just for practical reasons if nothing else.
And just remember when and if you come back to the board, hiding is generally futile. Some of us who are very observant will figure out your new handle or it'll get spilled somehow.
So if you sincerely wish to go in a different direction, might be an idea to just stand tough, keep your current handle and work on your current reputation, whatever it may be.
In literature, today's scorned can often be tomorrow's hero. Sometimes, that can follow in real life. Shrug.
Again, good luck.
