If you don't like dealing with the check point guard, choose to have sex with him, and put a hypnovisor on during the scene, then put on several restraints so he can't take it off. their is no need to actually have sex with him... this will make every fight with him instant win, saving you the trouble of fighting him or opening the cheat menu
Also the checkpoint guards fetishes say he likes all of the sex options but his arousal doesn't go up when I fuck his ass
