Nothing will fit in there!

So I’m a virgin but masturbate sometimes.. I’ve been trying to fit a dildo in but I can never go in far. It just will not fit and I don’t wanna force it because I’m scared it’ll hurt.. I can only fit two fingers in. I once stuck the end of a vibrating toothbrush in (clean one lol) and it went in a lot but it wasn’t even thick so it didn’t hurt nor did I feel anything, it didn’t even break my hymen. I want to try vaginal masturbation so that’s why I’ve been trying to use a dildo.
