"I am 17 years old and have willingly been seeing a 22 year old. Due to how certain states have different laws i was wondering if this was legal."
*** If by 'seeing' you mean having consensual sexual contact, that would not be 'Criminal Sexual Conduct'. Here is the applicable state law:
"SECTION 16-3-655. Criminal sexual conduct with minors.
(1) A person is guilty of criminal sexual conduct in the first degree if the actor engages in sexual battery with the victim who is less than eleven years of age.
(2) A person is guilty of criminal sexual conduct in the second degree if the actor engages in sexual battery with a victim who is fourteen years of age or less but who is at least eleven years of age.
(3) A person is guilty of criminal sexual conduct in the second degree if the actor engages in sexual battery with a victim who is at least fourteen years of age but who is less than sixteen years of age and the actor is in a position of familial, custodial, or official authority to coerce the victim to submit or is older than the victim."

"On another point could i move out at 17?"
*** Of course you could move out. Then, your parents could contact the police and they would haul you back home. SC law defines a 'child' as anyone under 18. As such, you are under their legal 'control', until then.
"SECTION 20-7-30. Definitions.
When used in this chapter and unless otherwise defined or the specific context indicates otherwise:
(1) "Child" means a person under the age of eighteen."
