This is the first time I'm using a tampon and I was having trouble getting it out. After an hour I relaxed and pulled it out, is this normal? I used lites. Is my vagina too small? I feel like its blocked by something. Putting it in was no problem.

It probably was behind your pelvic bone, which creates a little ledge (that actually helps hold the tampon in a bit). Yes, I spent many minutes over 35 years getting tampons out with some difficulty, towards the end of the week when the flow was light and the tampon dry. When it was soaked mine practically fell out.
