BnN,
Welcome to the forums.
Most swingers sites, including this one, have groups in which people who are searching for a particular race can hook up. I don’t know of any sites that have space set aside for people who are looking to exclude a particular race. The way your post is worded, and I hope this wasn’t your intention, it seems that you are trying to be exclusive.
I know that some people will want to point out that there are groups that specify “BBC only” or “BWC only”. It may seem like a fine line between that and what you seem to be requesting, but it’s an important distinction. Racial exclusion should never be part of our lifestyle.
