Can't give any advice about saying no accept swallow your fear and say it. I am afraid to say no in any circumstance, be it sex or second helpings. I just swallow my fear and remind myself that it is my body and my right to say no. Doesn't make it easy but I hope with practice it will become easier. It does doesn't it?
