I wouldn't say there are rides are won't go on.. but rides that I'm ok skipping on repeat visits. I did everything at least once.. most rides I LOVE!!!
A few I just can't go on again.
I'm allergic to whatever they put in the water at GRR, everytime I have gone on the ride I have broke out in a rash.

My kids are old enough now that they can ride by themsleves .. I feel bad that I can't enjoy the experience with them. I love the ride, don't like the itchy aftereffects.
I don't particularly like Mailboomer but if DH convinces me maybe I will give it another try.
Same thing with the swinging gondolas, made me nervous.. but if I'm in the mood to be thrilled.. and the line isn't an hour long!.. I will go again if the family wants to go.
I went on It's tough to be a bug on my last family trip.. hated it the first time and avoided it for years.. hubby convinced me we should go since BIL had never goen before.. It wasn't as bad this time around. And I enjoyed the experience.
We skip ones that don't have good repeat value.. Mulhulland Madness (boys do single rider, too squishy for hubby and I ), Honey I shrunk the kids (yawn), Golden Dreams (yawn...only if we are tired and hot.. good place to relax), Lincoln (once a trip only, gladly wil go back when it returns to see if they changed anything).
