Roller coasters are tricky for me since I have minor motion sickness and a fear of heights. My first official rollercoaster was Mt. Everest at Disney World. I couldn't walk after I got off it because it went backwards. I've progressed, with the Disney World Barnstormer being my first enjoyable rollercoaster. Then, I progressed to the Carowinds Goldrusher and the year after that I was able to get on the Vortex. Then I went back to Disney and Universal recently and if I remember correctly I was able to ride Space Mountain at Disney but I think that was the only true rollercoaster I rode. Then at Universal, I was able to ride pretty much everything except the dragon themed rollercoaster in the Hoggesmeade part of Universal and Rockin Rollercoaster.
