My (33F) partner (30M) not putting on clothes after showering

My partner (30M) and I (33F) have been together for 3.5 years. We moved in together 3 years ago and it is just the two of us in the house.

I feel that we have passed the honeymoon phase of our relationship. I don't think intense physical chemistry can be sustained long term in a relationship in the same way it usually is at the start (maybe I'm wrong?). Anyway, my sex drive has dropped and I just don't feel like engaging in intimacy much these days. I have no interest sexually in anyone else, for that matter.

My partner had gotten into the habit of wandering around/sitting around the house naked for hours every night after his shower. After a while, it just got old for me and I requested that he start putting his clothes on after drying off from the shower.

Now he's really upset and says that I find him repulsive looking and disgusting, that he feels unattractive to me. I reassured him multiple times that this was not the case however he doesn't believe me and remains salty.

Honestly- I don't find him unattractive/repulsive at all but I just got sick of him pandering around nude all the time. However he enjoys nudity.

Was I unreasonable in my request?

EDIT: there is baggage in our sex life which started a couple years ago when I disclosed to him that I don't orgasm during sex due to nasty side effects of the antidepressant meds I was taking at the time. He said he understood, but drastically lost interest in having sex with me from that point onwards. I felt so incredibly hurt and regretted telling him this, because I didn't want things to change between us. I have since come off the meds, which has enabled me to orgasm. However, my interest in having sex with him has still declined. Not entirely sure why. So, over time, we ended up going opposite ways with our sex drives.

EDIT 2: yes, I totally get that he has a right to say no and continue staying hot. Whatever, that's his choice. The main issue here is that he is interpreting what I asked as me telling him that he's unattractive and disgusting, which isn't true at all. Like one commentator put, I'm just a clothes person and he's not. In my view, i just made a request, which he has the right to say no to.
