Naughty Thoughts Of Bbc's

I'm a married white man in a sexless marriage. Lately I'll jackoff and think about bbc's. I've been checking out bbc's on the internet and chat rooms. I'm not sure why I do it but can't stop thinking about them. I've been wondering what it'd be like to try some bbc. So I set up an ad to see if I could get any responses. I hope to get a few replies and set something up. I want to try both oral and anal. Any advice before I do this would be appreciated. Thanks for reading my confession.
