, David Konopka goes by all sorts of user names and is on tons of dating sites. He claims he’s single but isn’t.. he even got a women pregnant her met and left her.. he has ED.. says he’s amazing in bed and has no issues. When he fact he’s the worst I’ve ever had.. and that’s only when he was able to keep it up.. he’s cheap and will try to get whatever he can out of you. And will always play the victim.. watch out.. by now I’m sure he’s carrying something. If I could post a warning on every dating site I would..
