Help!!!!!!

Ivory
So, my bf and I have been sexually active for a total of 3 months. Problem is, I can't stay still while he is playing with my clitoris. I always feel the need to close my legs and/or squirm away. I have tried to keep them open, but I feel like it's just too intense. I have no problems while masturbating though. He can't even hold me down...... He wants to tie me up and see if that would work. Is there anyway to keep me from doing those things? Has anyone else had these problems?
