Tight testicles all the time,normal?

hi, 46 male, for a long time now, my testicles dont seem to hang, they always are tight like i have been in a cold pool. they used to hang half way down my peni5.
i know they hug up and hard when cold, but this seems most of the time.
it looks like i have one round ball its that tight.

wont let me add a pic for ref

is this something to worry about? i thought as you got older they sag.
