I pegged my bf but didn't stop when he begged me to.
Could you tell me more about what happened?
He asked me to stop, but I didn't even though he said no.
It's completely unacceptable to keep having sex with someone after they've asked you to stop. You have to make sure that there is consent when doing sexual acts, and as soon as someone says they want to stop, then consent is no longer there.
Dude stop being such a fucking buzz kill, It's not a big deal.
What you did is basically a kind of sexual assault and is definitely a big deal. Think about how you would feel if you were violated sexually. If someone tells you to stop doing something sexual you need to stop immediately.
