The PSN ID is associated with a specific SE account. To play with a different SE account, you have to log in to the PS3 with a different PSN ID (in this case, yours).

Its worth noting that if you do not have the PS3 version on your SE account (i.e. you haven't bought a PS3 version for your account) you will not be able to play even with your own PSN ID.
