It's only the average experience if you have shit therapists.
I had two different ones as a kid/young adult (years apart) and they both fucking sucked and made me not want to do therapy.
As an adult (and someone who cares about their mental health), when my partner finally convinced me to go back I researched who was covered and would line up with my values/personality, and I interviewed a couple of them before I found the one that seemed to mesh with me. Spending the time to find someone who was LGBTQ+ and kink/poly friendly at a minimum was well worth the time spent.
Been with my therapist for over a year now, and I've made so much progress that both of my primary partners have commented on how much better I'm taking things.
Tl:dr - find a better therapist
