I want to say that I am not a good lover, and then what I should say is that my subconscious told him not to lie to me or something.

If you say it, the purpose is to let your QQ friends see it, which means you already have a goal. Since "he" is your goal, you should believe that your potential hints for "him" are useful to "him" and that he will not lie to you. You can say what you want, be as concise as possible, and it is best to use "you" as the object of your speech. If he is an emotional person, he will understand.
