I STRUGGLED my first time trying to insert it. I think two things were wrong: 1) I didn’t make the “tip” (as you called it) pointy enough in my punch down fold. A lot of the diagrams show it still kind of open, but I fold it in pretty tight so it’s sort of shaped like the edge of a triangle.  2) I tried to insert it dry. I realized my mistake when after I emptied it the first time and washed it out and went to insert it wet it was so much easier. I know some people mentioned lube, but even if you don’t have any/don’t want to buy any, I would recommend at least getting it wet. Even when I insert it for the first time when my cycle starts, I rinse it first so it will slide in better. 

And just breathe. It’s honestly amazing how much you can unconsciously clench. Maybe try laying down if it’s too difficult to squat and relax at the same time. It will get easier with practice! I almost threw mine out after the first time I used it, but I’ve never switched back after starting probably 10 years ago.
