I couldn't get it up and then she got in a car accident on the way home, are we doomed?

[TheWizard]

I am a guy and around six months ago I met this girl on myspace. We were like text buddies for months. We finally met a month and a half ago and I don't really know how it happened but the first time we hung out, we made out with each other. Well it progressed and we've gone further and further each time. It's a little complicated and I don't want to be judged but her and I are both in relationships so we don't intend on taking this further than just friends with benefits. Tonight though we were out drinking and we went out to my car and just started going at it next thing you know we were gonna have sex but I can never get it up when I drink, been that way since I was a kid. What happened, of course I couldn't get it up and she seemed really offended but then seemed to calm down and said that I was her best friend, she knows it happens and that she loves me. As if I didn't feel bad enough, on the way home, she got in a car accident. I told her I'd go help her but she said she had a friend that lived close by who would help. She text me and said she was fine. I feel crappy about it all and I'm like damn are we doomed now. I mean some people would say a friendship like this is doomed from the start but it works for us and I don't want to lose it over what happened tonight. I think the reality if the situation is that is we truly are friends and this ruins it then we weren't as good a friends as I thought. Ughhhh. I guess I couldn't use some kind words without being judged. I'm only human after all.
