It sounds like your inadvertently doing something wrong that is setting off red flags to the ladies.  

By the way, not returning emails is not standing you up.

I see a lot of newbies and I know it's difficult to get started and say all the right things.  
Giving any inclination that your not totally into the meeting or feeling wishy washy would be a red flag.  

Are you talking explicit or talking about money and sexual acts together?
Are you being wishy washy about meeting times?  
Are you trying to pin the ladies down on certain menu items before the meeting?

Have you read the newbie manual on the Newbie board?  

I hope things work out for you.  Perhaps try joining P411.

If someone wrote me an email as unintelligible as this post I would not have high hopes of meeting him either.  First impressions are important.

well, uhh....

blue lights on your Crown Vic?  you may wanna change outta your security uniform before showing up for your appointment LOL
