I know this isnt everyones thing, but perhaps he could try stimulating your anaus whilst doing doggy style, ...for me it wouldnt be much of a problem giving clit stimulation as i have long arms ...
Maybe whilst he is doing this position to you, he could pull out every no and then and rub his cock back and forth over your clit, perhaps moving away slightly and using his tongue on your clit and pussy, then going back with his cock.....just a few little ideas....
