Close your eyes and fixate on it being thicker (or she as tighter) than it really is ? If it even applies for that matter you probably can't tell the difference, so concentrate on busting your nut and the angle of thrust that is most pleasurable for you, it's not like she isn't going to move around to find that optimal spot and friction. Fantasizing it as better than it really is has gotten me thru a few lame lays. It goes both ways I'm sure. It's all good in the end.
