He never makes the first move

How can I talk to my boyfriend about wanting him to be the one who makes the first move. We've been together for 2 years and I said I love you first. I always say it first. I initiate sex. I am the one who is like "Let's go on a date." He never initiates ANYTHING. He is very... The words he uses to describe himself are 50 shades of fucked up. He told me this in the beginning he has a hard time getting attached and expressing affection. He has c-ptsd. Borderline personality disorder. Bipolar disorder. OCD. Paranoia. Severe depression. He has a lot of issues. He's medicated and talks to a therapist but I don't know if this is why he NEVER makes the first move but how can I talk to him about it?
