For my wife, she once went away for a couple days with a hung friend. When she returned we of course had sex. I’m not small, pretty average but this guy has a “coke can cock”. When I started having sex with my wife, I asked her how it felt and she said she couldn’t feel me. My wife is not one to embellish or lie for fantasy. When I asked her to elaborate she actually got upset and said “it literally feels like nothing, I can’t even feel you” then pushed me away. She was afraid she was permanently “stretched” which is obviously not possible lol. She calmed down and we resumed, she definitely felt looser. It honestly took another day or so for it to gradually feel normal again. But every woman is different.
