Well, if you don't want to put diapers after orgasm, there is only one conclusion - this is how sexually appealing diapers are to you. For most people - I'll relate to men here, having an orgasm means losing interest in women's body and actually women overall - this is due to hormone changes, that ejaculation has caused. The difference between women and diapers is that, women are a human being and you are attracted to them on the level above just naked body, but the truth is, that their tits and booty is nowhere as tasty as it was before you have ejaculated, right? You lose interest in this matter - same thing is with diapers, yet you won't cuddle the diaper, talk with it and see a person you love - you just see a sexual object that turns you on. Same with women, just naked body is your sexual object as well, but apart from this you are attracted to her on human - human relation as well, so even though her naked body don't turn you on anymore, you are still in love with her - because of who she is, which is definitely not the case with diapers. Once your hormones levels are setting back, you are getting turned on by wearing them again. All there is to it really, humans are really simple existences, after all we are doing everything that nature has made us to do.
