That wasn't my experience at all. Health insurance was literally three times more expensive for me throughout my perfectly healthy twenties compared to now as I'm nearing 40 (on an ACA plan).
If we are swapping anecdotes, my experience is the opposite of yours. I'm paying almost double what I paid 10 years ago, and my deductible is four times higher, with separate deductibles for drugs, and a smaller network of providers. Along with higher co-pays, and coinsurance now.
