her chemistry with our bull is better than her chemistry with me lately... how do i sit with this

M42 / F40, hotwife dynamic 3 yrs, one regular bull weve had for almost 2 of those. we have a good marriage. like genuinely good. but i need to say something out loud bc its rattling around in my head. her chemistry with him is better than her chemistry with me right now. like specifically right now, the last few months. its visible. its in how she lights up when his name comes up, in how she gets ready to see him, in how the sex with him is (i hear about it after) compared to the sex she and i have on a tuesday night when we're tired. and i know what ppl will say, "compare new exciting third with everyday marriage isnt fair", and yeah i KNOW that. i know its not apples to apples. routine marriage sex vs once a month special-occasion bull sex is rigged. but its still landing in me. and im not sure if im supposed to a) just feel it and let it pass, b) talk to her about it which risks making her feel guilty for what is literally the dynamic we set up, c) put more effort into our own sex life so the gap shrinks, d) take a break from the bull thing for a while so the contrast doesnt sting, or e) just accept that this is a feature of the dynamic and the contrast is part of the deal. how have you sat with this exact feeling. and how do you tell your wife without poisoning the well
