A week or so ago my LTR and I went out to the bar with a group of friends. We both were drinking but ultimately she was more intoxicated than me (nowhere close to blackout). We ended up going back to my place and had sex. At the time she was into it, literally asking for it. The next day she said it made her feel weird and that she couldnt believe I would do that so easily. This wasn't something new. We've had sex after the bar countless times. What dynamic has changed? How major of a red flag is this? And how should I approach this in the future? Our sex life and relationship as a whole has continued as usual after this though.
