Are we genuinely too old to start. F44 M46, kids just left for uni

so we're empty nesters as of september. youngest packed her stuff and drove off and we spent the first weekend just sitting in the quiet kinda... staring at each other. love this man, 22 yrs married, but we've been parenting for 19 of those yrs and we're looking at each other like, ok, what now. a few wines deep on a tuesday night and the LS came up. neither of us had ever really raised it before. turns out we'd both been thinking about it for ages and never said anything bc the kids were home and it just felt impossible. now they're gone and we've got this big quiet house and a lot of evenings and we're both like... is this the moment? the thing eating at me tho is. are we too old? like every profile i see on these sites is gorgeous late 20s couples in lingerie and im looking at myself in the mirror going "babe, you have a c-section scar, lower back issues and the boobs of someone who breastfed two kids for a combined four years". he says he loves my body and i believe him, but i dont know if a club full of 30 year olds is gonna look at us the same way. i know "age is just a number" etc etc. but pragmatically. is the scene welcoming for couples in their mid 40s starting from zero? are there clubs/sites/events that skew older? are we gonna walk in and feel like everyone's parents? genuinely asking bc if the answer is yes then maybe we just stay home and rediscover each other instead.
