Dysphoria is not wanting to put things in your butt in case it makes you feel more like a man, but now that you're a woman it doesn't give you dysphoria anymore, it confirms you are a submissive fucktoy...?
That is the closest I can get to trying to figure out what Kevin could have meant by "must have been dysphoria", but as you all can see, it doesn't even make sense in whole or in part. I don't think even he knows what he is saying.
He just doesn't want to stick things up his butt and for some reason feels he has to make excuses for it. But since he's not supposed to feel so much gender dysphoria anymore now that he's transitioned, that particular excuse has a time limit, what is he going to do when it runs out?
Kevin, if you don't like butt stuff, you don't have to make excuses. It's your body, your rules.
I genuinely wonder if he was molested or raped as a kid. That plus autism screwing up what he learned about life from it, plus a healthy dash of refusal to face his problems would explain him wanting to transition, being extremely deviant, trying to avoid anal stuff and being intimidated by booking very small pills, breaking others' boundaries constantly, and all that vast amount of cope.
