Just a quick bit of advice for the gents here.
It's been my experience that very few of the guys who email me have read my profile. Men have admitted to me that they only look at the photos before responding.
If they had read the profile they would have seen my location/ethnicity preferences.
If someone contacts me who does not fit my preferences I delete the unread email.

Not reading the profile and fitting the preferences could be one reason some of you are not getting any responses.

Also, I think the worst emails I've ever gotten on a dating site are the ones where the guy just gives his name and number.

Last one I got like that said
"What are you doing on tonight?" and a phone number.
I wrote back. "What am I doing tonight? Not you!"
