Don't touch the pin then, why do you feel the need to touch it?
Your body works as an antenna. When you touch the pin you inject 50/60Hz as well as other noise into the pin. At a guess, it might be that you don't have the correct pull up resistors on the SCL/SDA pins. Should be around 2k2 methinks.
