I’ve read on here orgasms by women trigger a pairbonding chemical in their brains.

She says she still cums when it hurts after 30 minutes or so. On average she cums 5-7 times every time we bang.

My question isn’t about making it hurt less, more so the pairbond theories. I’ve tried lube, foreplay and going slower.

What I am asking here is, are the “pairbonding” chemicals released to the brain for only pleasurable orgasms? Or painful ones too ( like my LTR says after 30 minutes of banging).

She claims she cums just as much after 30 minutes ( we usually bang 45 mins or so) but it just hurts after 30 mins. We bang 5-6 times a week.
