Do cuddles and hugs die down the longer your in a long term relationship?

Basicly me and my partner are very cuddly and hugging and I wouldn’t change it for the world, but my mum and her partner don’t hug or cuddle anymore and her friend and her partner of 30 years they don’t have any intimacy. basically said to me enjoy it while it lasts

And now I am worried if this happens in most relationships. ?

Do cuddles and hugs die down the longer your in a long term relationship?
