My first husband was very much immature, but then we were both teenagers, 19, so not a lot of experience in life. He had only had one cock before mine so was impressed with what he was getting from me. For a couple of years we didnt really socialise much and our sex life was amazing. TYhen we did a party, both got drunk and he was led off by the host and fucked by a big cocked guy. After that he always wanted bigger, even with a strap-on, and yes, huis hole did feel bigger and not as tight when I did fuck him. Nothing I could do would impress, so eventually he left me in search of bigger harder cocks. So, for some, size does matter.
