AITAH for asking my boyfriend to respect my alone time?

I (27f) and my boyfriend (26m) having been dating and living together for nearly a year. Before moving in I enjoyed moments to myself and needed it to decompress. When I moved in I explained that I need 10-20 minutes of being alone to decompress and then I’m all good to go. He did not like it, he felt at first that I was mad at him every time I’d say I wanted to be alone in the room for a moment he’d beg me to stay. Eventually I caved in and gave up my alone time together to reassure him. When we get into arguments and I need to walk away to take a breather to collect my thoughts so I can handle the situation better, my boyfriend hates that I do that. He’ll immediately follow behind me calling me immature for walking away and demand to continue said argument bc he wants to solve said issue. Recently I’ve been put on new medication that has revived my libido. Unfortunately, it takes me forever to climax (30 to an hour) it’s always been this way. Since my libido comes in waves and if I can’t ignore it I tell my boyfriend that I will take care of myself and to please not knock on the door and if he needs me to text me as I always responds. He did not listen, each time I was close he’d knock on our door asking what I was doing and I’d get frustrated telling me he knows what I’m doing bc I told him and I told him to please not knock bc if I continue I’d have to build it up all over again to climax. He continues to interrupt me or ask to talk when I specifically tell him not right now. When I get done he just mopes in bed upset that I got after him even though I specifically asked him to leave me alone bc it takes me forever to climax. So AITAH for asking my boyfriend to let me have alone time?
