Do you really lose libido as you age and get older ?

Me and my bf had a discussion where i believe older people can still have a pretty normal libido whereas he believes when u get older you lose the desire due to biological reasons
And im just wondering if I could get older folks to give me their opinions as I’m curious

I rly hope this question doesn’t get me banned I reviewed the guidelines and it seems to follow and I looked for banned topics and nothing i saw would say this was not allowed to ask
