My boyfriend M (23) doesn't show the same sexual activity with me (28)

My boyfriend 23 hasn't wanted me 29 for a more than a month and half now.

I realize that I'm a little bit older and , according to him, I'm too thick and hung... to preface this, I know that this is common and I have not pressured him as he not pressured me to do anything different or asked e to change anything since he has explained his struggle with having a low sex drive to me. When we first met he didn't mind me choking him and having my way with him, even though that might be too much for some. I loved experimenting and finding new ways to pleasure each other, especially because i like being the dom in the relationship. Do any you of you have any insight as to why he might not have wanted to have sex for longer than a month? I don't mind it, honestly, because our our relationship is greater than that, but I still wonder. I have learned, based on his posts, that my dick may be too big or thick, but I don't know what to do based of that information. Am I supposed to make myself smaller? That's not possible... so what can I do to make it easier for him?
