I've been dating this guy for about a week and we haven't had sex yet, and tonight he told me that he has a pretty big dick. Like big enough that previous partners have been scared. Now I'm freaking out just a tad... for one thing I'm a bit of an anal virgin and I have a feeling I won't be able to take him. Another thing, I'm just average, nothing special, I just can't measure up to him. Any advice? Should I try to stretch out my ass lol?
