Hi Dowa, Somewhere in all my reading, I have read that lyme can be transmitted sexually. I think it is still a controversy in the medical world, like everything else about this disease. I have Not read about kissing as a problem, but Have read that blood transfusions can pass it along. And somewhere they talked about urine, but I can't remember what it said. Maybe you can find some research papers on the web that can clarify these things for you. Best wishes. bablymers mom
