Hymens don't break. They stretch. It's a really common misconception that hymens break. Sorry. Just felt the need to comment on that because I don't think you should just try pushing harder. That would really hurt and probably not accomplish anything.

The advice here was good. Small plastic applicator. I advise using a finger to just get a feel for what direction your vagina goes. If you try to shove it in the wrong direction, it won't go. That sounds really painfully obvious, but sometimes it isn't always easy to figure out. I insert the stupid thing in a slightly wrong direction all the time and it is unpleasant.
