How do you stop comparing your 47yo body to a 28yo body when she is right there in the same room

this is gonna be a vulnerable one so bear with. me 47, dh 50, in the LS 6 yrs. last month we played for the first time with a couple in their late 20s (she's 28 he's 30), match was great online, drinks went really well, group play went really well TOO if im honest, and yet I came home and quietly fell apart in the bathroom around 4am bc all i could see when i closed my eyes was her body next to mine. shes lovely btw. literally not the issue. very kind, no weird energy, no comments. its entirely happening in my own head. but the contrast was loud — skin tone, where the weight sits, the shape of stomach after kids vs without — and ive been comparing in a way ive never done with women in my own age range. weve played plenty with couples in their 40s and 50s and i dont do this. with her it was instant and i havent been able to put it down for a month. dh is being lovely and reassuring and saying all the right things but heres the bit thats hard — he ALSO clearly enjoyed himself that night, which of course he did, and even tho i logically know him enjoying her doesnt subtract from him enjoying me, my body keeps reading it like a math problem. i dont want to never play with younger couples again bc one of them activated this in me. but i also dont know how to be in the room with a 28yo body and not have my brain hijack me. ppl with bigger age gaps in your play, how do you do it. is it a thing you wrestle every time or does it fade. i need real stories not just "love yourself queen".
