My 2 cents: I really enjoy it doggy, it's fun and very stimulating. Although I always hesitate (about 2.5 seconds) you see I have no idea if that's sexy, never saw myself from that angle
However it is not a 24/7 option for me either, it's wonderful and always welcome in the middle of my cycle but after baby making time my cervix gets in the way of why I love doggy - deep deep DEEP penetration.
Homeword: You can try bracing one knee/leg up, it's more freeing but takes some forethought. Then she'll look like a doggy for sure. Sorry, had to.
