I've had two of these problems. I'm not sure if it was about my size or not.

One situation was very nice, we'd meet up casually for coffee, then we'd go to either of our places and fuck. She was very good in bed and knew all the right moves. We still meet up sometimes now.

Another situation was not good. You see, I am a swinger. I do not get into relationships because, truthfully, I hate relationships. I hate what they take and I hate being bound to one person. Anyways, she couldn't take no for an answer. My best friend and I got drunk at the bar and we both took her home. She wanted to 'experience her first threesome.' Anyways, she was disgusting, and we were drunk so we didn't know. My bud isn't exactly HUGE, but he is above average, and I made the mistake of going at her first, so she was a little loose for him. When he filled her she kept making comments about how small he was (and 7 inches isn't really small.) We both got really pissed at her. She was sucking on me while he was going at her down south. I made a gesture to my bud, then pulled out of her mouth and blew it all over her face. I thought she'd just get pissed off and leave, but she seemed to enjoy it... which was fucked up. So we both finished up and she left. But we made the mistake of giving her our phone numbers earlier that night, and it seemed like every day she was calling me. So after about 50 calles I called the phone company to see what they could do. I had the number blocked and never heard from her again! :)
