How to Correct This Huge Mistake?

Okay, so I've been texting this guy for all of about five days. We're super into each other. And sex hasn't been mentioned at all--until tonight. And it's all my fault! He was out a concert and got a little ****-faced. So we're texting, and he's about to go to sleep, and he brings up "room service" and he'd like his "pillows fluffed". So, stupid me plays into this whole sexting thing, and it just went downhill from there, if you know what I mean--or uphill, if that's how you want to look at it? I'm extremely vulnerable right now because I haven't been with anyone for about five months, and I know that's no excuse. I don't want to come off as a tease, and I don't want to scare him away, because he's really awesome. BUT, I also don't him to think he's going to get some on the first date, that's just not my style. I have self-control, he just caught me at a weak moment. Is there anyway I can fix this, or did I just screw myself over? Help!
