Any petite ladies known to be ale to take it deep?

This may be a strange question or not in the right forum, but:  l enjoy companionship with petite girls (5'1 to 5'6), thin.  I don't think I'm "huge" but I guess I'm longer than average and recently my experiences have been with girls that can't quite take it deep (even in different position).  I certainly don't want to cause any discomfort and find myself "taking it easy". I'm just under 8"...not thin, but not a beer can either..lol

Any ladies to suggest?  PM ok
