I am looking for the Mr. Marcus model dildo. This one seems like a good start. Hope I can find it in the Nehterlands.

Material is key
 

I agree with many comments above. The ones that have that heavy latex smell and texture aren't good for my wife at all. She has no latex allergy but she can't stand the taste if she wants to fantasize about sucking BBC while I am fucking her. The "real skin" types don't usually have that odor and texture.
It isn't all about being huge for most women from what they tell me. Black guys are generally more dominant and aren't afraid to tell you what to do. Thats the allure for my wife. If you're really packing 8" the size thing isn't an issue believe me. If anything go for more girth than what you have. As someone said above 10 or 12" isn't going to go all they way in anyhow.
