If a black hole has the same mass as me, then why dont i suck everything at my center of mass?
Because you are somewhat larger than your Schwarzchild radius.
In order to turn into a black hole and start experiencing exciting things like Hawking radiation, you'd need to be compressed down into a ball about $10^{-25}$ meters in diameter, about one ten-billionth the size of a single proton.  At that size, you'd have a hard time sucking anything in: your gravity falls off quickly with distance, and even most subatomic particles will just bend their paths slightly as they pass you by.
