I've swallowed once. I don't know if it is a regional thing...I'm from the south or just a generational thing (I'm 52) but I had no idea guys even expected girls to swallow until I was nearly thirty and I started dated this guy from Denver. He told me he had not had a decent "head job" since he moved south. He said southern girls wouldn't swallow.
I made up my mind to give him his first decent, southern head job. I swallowed...attempted to swallow I should say. I don't know what that boy had been eating but I ended up gagging over the toilet. The minute his cum hit the back of my throat it was like an explosion and everything in my stomach started coming up. The taste of it was horrendous. What an experience!! My last attempt at swallowing also.
Shortly there-after I married my ex and he never made an issue of it. I asked him once didn't he want me to swallow and he said, "Why the hell would I ask you to swallow something I wouldn't swallow myself?" With us it was always foreplay and that suited me fine cause after that first experience I was a bit afraid I would humiliate us both by gagging.
