I must agree.
This was/is also the case with Marry Queen and Christy Charming. And while not exclusively true, this was mostly true in the case of Arwyn/Simi and currenty is with Katerina Hartlova for the majority of their modeling careers. Unfortunately, this trend also seems to me manifesting itself with gorgeous newcomer Tracy Loves.
While some say that we should be thankful that they do any B/G at all, and that if it takes their doing it with their boyfriends then so be it - there is a good deal of truth to that. But it still gets pretty stale seeing these amazing babes doing the same guy over and over again.
As such, my favorite has for years been Lexi Belle. While very attractive, Lexi does not have, IMO, the sheer physical allure of these others, but she more than makes up for any deficiency by her tremendous enthusiasm for sex that none of the others possess. Over the years she has fucked hundreds of different guys on camera, and such devotion has turned her into a true multi-orgasmic sex machine that I find almost overwhelmingly attractive.
