Rope, great story. Add yet another advantage to having a big dick: girls are willing to overlook getting vomited on.
For me, I've never been laid just because of my size, but I think it's definitely moved up the timetable with a few girls, so to speak. On my first date with my last long-term girlfriend, for example, we were rolling around on the bed after having a couple of drinks, making out with our clothes on. She reached her hand down to my inner thigh, I think intending to do a slow, sexy slide up it until she was holding my crotch. My cock threw off her plan, though: it was already hard and stretching down my leg, so as soon as she made contact, she felt it. She gave a little squeeze to feel the girth, then suddenly pulled her hand away and broke the kiss with a surprised "Whoa!" That's as far as it went that night, although she seemed very, very affectionate as I was walking her toward her cab.
On our next date the following week, we were again making out, and this time she had unbuttoned my pants so that the outline of my cock was clearly visible through my boxers. She gave it a few tentative strokes through the underwear with her face showing a remarkable combination of lust, concern, and contemplation, as if she were fighting with herself to decide if she could take it out or not. She ultimately didn't, but she did on the next date and we got it on like a starving man devouring a hearty meal.
This probably doesn't seem that remarkable -- laid after three dates? Big deal! -- but you should understand that this was an extremely demure, slightly older woman who had gotten out of a long-term relationship that had led her from England to the United States, so she was extremely cautious about her romantic entanglements. She admitted to me later that she had been "intrigued" by my size on the first and second dates; if it hadn't been for that, it's likely that she wouldn't have slept with me until four or five dates in, and if it had taken that long, I may have just given up in frustration. So my size may have actually saved our budding romance.
