The vagina has a closed "end". It won't really go anywhere. You can insert it as far as you'd like, but be aware that, if it does get put in some awkward place, it may require lots of swearing and awkward movements to get it out. However, that'd be a very rare occurance. Most of the time, it'd be a straight in/out. So put it where it feels best!
As for not orgasming from vaginal stimulation online, I think the statistic is that only 25% of women can do that, so don't feel left out. I can't either.
