Sometimes when I put a tampon in it hurts and other times it glides right in with no problems. The times it hurts it feels like there's something in my vagina blocking its path. One time I just kept pushing the tampon in (probably not a good idea, I know) and it felt like it broke through something. After that it didn't hurt at all. I'm pretty sure the pain has nothing to do with me tensing up down there, and it's also not because I'm bleeding light either. I'll have the same flow and it will go in easy the first time, then when I remove that one and put in a new one it will feel like what I described. I use regular Tampax Pearls. Anyone else experience this?
