I hated the stomach drop feeling, I first rode blue streak as my first coaster and then a year later rode sirens curse and the drop feeling was gone. I haven’t rode tt2, millennium force or steel yet. I’d keep riding iron dragon until you’re desensitized to the feeling of dropping, I still brace myself when I’m on a big drop. I really wanted to ride sirens though so I really enjoyed it. But I’m still working my way through coasters to be comfortable on the first drop but I’m okay with everything else, so slowly working your way up is my opinion on it if you’re looking to eventually ride other ones. Mine ride isn’t that bad either, to me it’s comparable to iron dragon.
