Oh, man... I can't second Anormalguy enough on this one. If I was her, I could understand the nervousness and the sexual difficulty--that could actually be kind of cute. But the sneaking out would be a VERY VERY big deal. You don't do that. Now at best she's puzzled and at worst she feels cheap. You've got to go explain and clean that up RIGHT NOW. Not later. Now. Or sooner.
And then here's what I recommend. Let her know you really want to get over this thing, and you want to get over it with her, and it might take some patience and understanding on her part, which she's already displayed in abundance, and you completely appreciate it and are grateful for it. Then next thing? I'd set this up: you're in your usual masturbation situation--so, in front of the computer, the porn is happening, whatever. Have her be come in when you're ready. Leave the porn on, and go from there. And if things start not working, have her go away again until you're ready to go again.
I know for me, if I've had a erection for any length of time and it goes away, getting hard again takes some doing. So don't let that happen. You might need to masturbate to stay hard--that's fine.
Don't run from this thing. This is a "take the bull by the horns" kind of situation. Giving up on it will make it a hundred times worse next time.
