If you can afford/find a good, reputable dog behaviourist, I think someone like that would probably be able to help you. There’s a chance there’s something about the way you come across to dogs that they don’t like (including being as tall as you are - you’d tend to tower over them and they may feel threatened by that? If it is that, there may still be things you can do to help them feel safer, but I’m not an expert) but I’m only going on what you’ve written and speculating a possible reason. Someone with the relevant skills would have to observe you, behaving as you normally would around your dogs, to really know what was going on here.
