gas causing pain during sex?

I always have severe bloating and gas that never comes out, I've tried gas-x and non name brand gas-x. nothing works. and when I do finally release gas sometimes it's painful. the gas even affects my bladder making it hurt to pee from the pressure in my abdomen. when I'm finally gas free it won't hurt and have pressure. either way since the gas is so deep in my abdomen down there just feels uncomfortable during sex and makes everything pained and achy, is this normal?
