When I put on a tampon the applicator doesn't go as far as it is supposed to, Why is this and how can I make it go all the way?

How old are you? Are you a virgin? If you are a virgin it may not go in all the way, and you may want to stick to pads as pushing it in all the way WILL break your hymen. Which isn't a HORRIBLE thing (depending on your culture) but it can be painful and not worth the aggervation.

Other than that, if you are not a virgin anymore, I would consult your doctor. Its possible you have a small vaginal canal. Some women are like that.

Good luck hon. And get back to me with details.

I wouldn't worry about it but all I can recommend is just exploring yourself down there. You can't visualize where the tampon is going to go unless you know exactly how it is down there. Hope that helped :)
