I have an ongoing problem in bed. I've been told I'm large and that it hurts when I'm all the way inside. Every girl I've been with has told me this except my ex (who was a virgin, oddly enough). The last girl I dated never got fully used to me, and we were intimate for 3 months. Our sex life became dull after a while b/c she could only tolerate about 2-3 positions. I'm with a new girl now who I'm very happy with. However, sex is difficult for us b/c she's very tight and I'm pretty big. I've heard that girls will stretch over time to accommodate a larger penis. I was just wondering if this is true. Any help or insight is much appreciated.
