What’s the right amount?

So my boyfriend and I haven’t been having much sex. It’ll be almost a month of the 24th since we’ve done it. And I want to all the time but he pushes me off when I try. Since May it’s been like four times a month if that even. Is that a normal amount even? Like how much sex per month is a normal amount for most couples? I’m really curious cause I’m a horn dog and for me even just four times a month is too little. I’ve tried bringing it up multiple times and he’s done nothing to change it. I’m worried our relationship is doomed.
