Burnt_Out, you've been given lots of helpful suggestions here from some very good and experienced members. I would like to suggest that you do not try so hard in your profile, be the real you rather than making yourself look like a superman type. I hope you will take my suggestion at face value rather than (more-or-less) saying, 'Yeah but...'

You've also said that you have had several girlfriends in the past, I would suggest you look at where these went wrong rather than writing 'thousands' of messages to women on these dating sites. Maybe you should try another technique and learn from previous experiences.

Look outside of yourself and learn from others.
