LS has gone stale at yr 13, what actually re-injected energy for you (not generic advice please)

sick of vague answers like "communicate more" so im asking specifically. f45 he 47, married 20 yrs, in LS since 2012-ish so 13 yrs. last 18 months its felt stale. like we still play but theres no anticipation, no charge, no "we are getting away with something" feeling. it's just... a thing we do bc we've always done it. ppl say "try something new" but new what. were not gonna start a podcast about it lol. i want concrete answers from other 10+ yr couples. like ACTUAL things that re-injected energy. not "talk to your partner" not "be present" not "go to therapy". like — specific format changes, specific kinds of trips, specific kinks you finally tried, specific scene changes, specific people, specific anything. things that for YOU shifted it from grey to color. bc i can already feel ppl warming up the "just rediscover each other" reply and i love you but no. tell me what you actually DID. ill compile and try the most repeated ones
