The hardest lesson to learn when it comes to love, is to learn to accept it in the ways that your partner is willing to give and show it.
I'll address your obvious issues first.
1) Stop being passive aggressive. State your needs up front. Statements like "I must not turn you on anymore." are not only emasculating to him, but generally just harmful to your own self worth, and completely unhelpful in resolving any problem what so ever.
2) Stop being passive aggressive.
3) Stop whining. It isn't attractive, it doesn't make you sexy, and it doesn't make him want you any more.
4) Dress up, wear makeup, make yourself look nice so that you feel sexy. Do it for yourself, not him. If he won't notice you, then some other man will.
5) Don't do his chores for him. If he agrees to do it, kindly remind him that it needs done, that he agreed to do it, and don't ever do it for him no matter how much it bothers you.
6) Stop acting needy. Be confident. Don't ask him if he wants sex, instead wake him up in the morning with his cock in your mouth. Hell, just masturbate in bed next to him, or jerk him off. Initiate sex without asking, just do it. Get some lingerie, get him a steak dinner and a beer, flip the ballgame on, then sit in his lap and feed the steak to him. When he's done eating give him a blowjob and see where it leads.
Basically, stop being a pussy about your needs. Make them known, tell him that either they're met or the relationship gets closer to ending, and be honest about it. It's a need, not a want. It's part of what you require for the relationship to be healthy and whole. Don't emasculate him, but let him know that he isn't keeping up in his manly duties.
Hold him to a higher standard. Don't let him get away with crap that is unacceptable. (Such as him not doing his agreed upon chores.) If he loves you and cares about the relationship he will make an effort.
But your comments about his masturbation, lack of love, not turning him on make him feel inadequate and like a failure. Men already have huge complexes about this to begin with, so doing things to prey upon that will not net you good results long term.
He's an adult, treat him like one and expect him to behave like one.
