Not sure if this is wsr. If not plz lmk so I can report my own thread so we can rip this down

My gf gets a pulsing feeling (almost like a heartbeat) in her lady parts when we kiss (we are waiting until marriage to do the reproductive dance). What is that about? I know what it means but; what’s the biological function? Is this common? What does it mean when we get married on the wedding night?

My apologies if this isn’t /wsr/. I don’t have any ad blockers so I don’t want to ask on a red board
