I am just trying to give you some ways to think about it. You don't have to "just get over it" right away, because clearly that is going to take some doing. But you do need to show willingness to focus on the other things as well.

Long term romantic endeavors require all sorts of compromises, many you don't see coming right away, and some are far higher than you might imagine. This goes for literally anyone you might meet, vagina or not. If it isn't PIV sex today, then it might be relocation or finances tomorrow. If you are serious about her, think about what sacrifices you might be willing to make for her for the sake of your relationships. It sucks to be forced into thinking about it so early on, but this isn't going to go away. Talk it out with her. My guess would be that she has been dreading telling you, and her worst fears are being realized. If you are serious about making it work, you will put some of her desires before your own (and hopefully she would do the same).

And if it turns out you really can't get over the lack of vagina, then hey that is you, and that is totally ok. Just don't lead her on by avoiding the issue altogether in that case.
