Wow okay this has sparked quite a debate. Looks like I need to provide a bit more context. Sorry I can’t write it in the first person.
Man is a rugby player, woman is smaller side of average. Both mid 20s.
Went on nice date. 7th or 8th date and 3rd time it ended with sex. Quite a bit of alcohol drunk, back to his house, enjoyable PIV sex, woman took a Valium before bed (has anxiety attacks, helps her to sleep), sleep.
Early next morning, both wake up pleasantly drowsy and hungover. Have consensual PIV sex with no condom. Man orgasms, the result of which makes everything slippery and lubricated down there.
Both naked, man gives woman his rugby shirt to wear, says he finds it hot to see a woman wearing his shirt. Okay fine. All cozy and pleasant. Both lie down again, man spooning woman. Woman dozes off, man probably does too.
Woman wakes up to neck kissing and such, man is clearly horny again. Okay fine. All still feels sleepy and sexy and pleasant.
Man is spooning woman tightly and then, without warning, they are having anal sex. Woman can’t quite process what is happening and doesn’t do or say anything. Her thoughts at the time were, is he doing this on purpose? Embarrassment, shock, why didn’t he ask, relief and surprise that it doesn’t hurt, annoyed that he didn’t ask, wishing she’d been given the chance to consider if that’s something she wanted to try, not wanting to upset him, not wanting to cause a scene, wanting him to like her, this is obviously what he likes, this must be normal right? Freaked out in case he doesn’t realise and it’s a mistake.
Afterwards man makes woman a cup of tea and toast which she doesn’t eat. She leaves and they haven’t spoken since.
