AITA for sleeping on my boyfriend bed without bathing?

I normally listen to Reddit on TikTok, but I made an account just for this.

Me and my boyfriend recently moved in together, and he is a clean freak. He will come back from a 9-hour shift and he will disinfect everything. When I asked him if he normally does this, he said he used to do it every 3 days, but since I moved in, he does it everyday. I had no idea he was this clean before we moved it.He comes home, disinfects while we talk about his day, and then takes a shower (the thing is, his cleaning time and bathing time varies; sometimes it takes him 30 minutes, sometimes it takes him 3 hours; I'm not sure why the time varies; he just says he has to start over because he made a mistake, but how do you make a mistake while wiping a table or mopping?(It is not like the mixture is wrong or something; he does it and then decides he needs to do it again.)

We have separate bedrooms because we both need our individual spaces. Last night, feeling lonely, I went to sleep next to him. but I hadn't bathed last night because I worked from home and hadn't gone out, so I felt clean from my morning bath. I was cuddling with him for 4 hours until he woke, which was about 4 a.m. He woke me up and asked me if I had bathed, and I said no. He actually told me to get up.He removed the bedsheet, pillowcases, and cover and put the bedsheet and stuff in the laundry. He disinfected the bed and changed the sheets and cover. Am I being insensitive, or is this an overeaction..

Tonight he came home and told me that I knew he didn't like when people slept on his bed without bathing and that I shouldn't do that again. I thought he was going to apologize for making me seem like a dirty skunk, but no, he warned me. I just want to know if I'm in the wrong in this situation. 

p.s he is a very good boyfriend and the first one to not do that weaponized incompetence thing.

Update: I talked to my boyfriend about therapy options and how I am worried for him. He said he had been seeing the university therapist for two months in his freshman year, but she was not qualified to treat his problems, so he stopped when he saw it wasn’t going anywhere. He talked to his insurance, and they told him to go to his primary doctor to get a referral, and his primary doctor gave him a list of mental health professionals he could see, but none of them are near our town, and our university is practically in the middle of nowhere. So he would have to drive 2-3 hours to see the mental health professional (he doesn’t have a car) and can't afford therapy without his insurance covering some of it. He admitted that he isn't mentally sound, but he has been trying to deal with it on his own.I asked him if he has OCD, but he said that the university counselor said that self-diagnosis is dangerous, so he was not sure. I sent him the website someone here gave me for a self-OCD test handled by a doctor. He seems to know that his habits are not normal, but he has a lot going on financially. He pays a tuition plan every month, but it is not too much because financial aid covers some of it, plus he pays half of our rent. I asked him to ask his parents or siblings, all of whom are adults, for assistance, and he refused, claiming that the only way they would give him money is if he lied about the reason, and they would never let him live it down if he asked for money (when I visited them, they seemed to have a really healthy bond; they seemed really close.) Can he get better without medicine ...
