Here's what you need to do...

When you contact a lady for the first time, send her an email with a note about you including your race (see below).

Hello Giamarie,
My name is John. I am a 45 year old, white male who has a little extra padding, but working on it. I am a computer programmer who spends my free time gardening. Right now, I am hoping to meet a young lady who will take away my work-related worries. I am a native of Minneapolis, though I travel often. I see you enjoy bike riding. I do as well. I think we would be a great match and I would love to hear from you. The best way to contact me is via email.

All gentlemen note their race when they contact me, even Asian ones, as I request this information on my website. Some ladies shy away from requesting this information, though it matters to them. So, I would suggest you draft an introduction email template similar to the note above. Send it to ladies when inquiring to meet for the first time. Of course, make sure to change any details of the email that would be particular to the lady in question.

Good luck!

Xoxo,
Giamarie

I have noticed that nearly all men who email me do mention their race, and many mention their height and weight. I do not use any of that info to determine if they get an appointment. I don't care about race or looks, all that is important to me is that they be respectful and have great hygeine.
And for her to reject you after the appointment was set and you were waiting for her... Very rude and unprofessional. Sorry this happened to you.
