My wife and I like to keep things fun and exciting in bed. Over the last two years, we introduced a little fantasy into our love life every once in a while. Even though we both have different tastes, we are pretty open with each other. Lately my wife has expressed an interest in black men, big black men. I like that it gets her excited but I'm starting to feel a little inadequate. I also like the dirty talk she does while telling me about her desires. So far this has all been a interesting addition into our sexual relationship, but now she wants to buy a big black dildo which I'm not too sure about. I’m average in size (six inches long and decent girth), but the dildo she wants is way bigger. I don’t want to be a spoilsport and I want her to experience things, but this has me feeling self-conscious and has even affected how I feel about our relationship. She says she would never actually do it with a black guy, that it's just fun, but I'm not so sure. She sure seems to have some pretty vivid fantasies about this.
