<human>: Ok, so a week and a half ago I met this girl who is really pretty, cool, smart, kind, etc. Basically she's awesome. We exchanged phone numbers (upon her request) and started texting casually. She's really into nature so we make plans to hang out and we go on a hike through the woods and have a great time. That night we hung out more at my apartment and cuddled a bit and talked all night. On saturday, we hung out pretty much all day and that night we made out a lot. We got undressed and I fingered her, but when she tried to give me head, I wouldn't get hard. We chalked this up to me being a bit nervous as it was my first time, and she stayed the night. The next day we stayed in bed cuddling and naping for a long time until she eventually left. Later on, I texted her to reassure her that whatever was causing me to to not get hard, it was definitely not her. She told me she was completely okay with it and didn't see it as a big deal. Then I made some dumb joke about how it definitely wasn't a BIG deal, trying to make light of the situation. She responded by saying that my joke made her cringe. Now she isn't responding to my text and I'm worried that my dumb little joke ruined what I thought was going pretty well. I'm really starting to like this girl and want this to work out, especially since I have never had a girlfriend before.
Any advice on what to do, or is this a lost cause?

Give me the gist of the text in a nutshell
<bot>: Me and a girl have been hitting it off but I made a dumb joke that made her "cringe" and now she's not talking to me.
