Can a decreased interest in sex attributed to other things as lack of attraction ?

Isn't a decreased interest in sex just the result of hormones slowing down ?

Testosterone starts to drop after 35 ( it even starts after 30). Then there's another rapid drop after 40. Same with women and menopause starting at 45.

I'm only 29 and I don't think I care about crazy, passionate sex anymore. I care about a life partner. Somebody I can talk to, laugh with and offer support to and also receive it.

I get that if you're 20 or 25, you hormones are raging like crazy. As did mine. But other things become more important as you age
