Not to be discouraging..but top and bottom positions are out....try side position...also, if you are experiencing dryness, do get a dr to prescribe an estrogen based vaginal cream, such as premarin etc., or you could benefit from a compounding pharmacist who could create a natural hormone just for your needs..the vaginal cream is not absorbed in the same way that pill forms are so don't be concerned with that, as I was at first, but learned later how the cream is basically designed to work different...some women insert vitamin E capsules about an hour before the intimate event when they do not want to use hormones..hope you get on the right track...I too have buttock pain...
