This is a bit strange. My BF and I broke up after almost 4 years together. During that time I was 100% monogamous. We broke up because of him finding someone new! Go figure. Anyway, for the last 4 years sex was great. I guess my ass was use to his cock and his cock only because I had a hook up last night with a guy I would say was only slightly above average in size and slightly larger than ex. But there was so much pain. I wouldn't figure it out. Any idea? Maybe he was thicker or maybe it's because it was over a month since I had sex. I just don't know what it was. I'd like to see the guy again but I don't want to be cringing and wincing again as he stuffs my hole.
