Is it normal when your vigina start beating?

Uh... U mean like pulsating? I'd imagine it's normal especially after certain activities so long as it doesn't hurt

Happens when body tense mostly your brain, women body is very mysterious most of our body is connected more with brain functions and psychological affects than physical.

yea it happens, if ur ovulating, or if ur libido got high, if there is some simulation that triggered those kind of emotions in u, then yea. happens to me alot of times even tho im like huh?!? bc im ace but my kittycat does that shit outta nowhere sometimes and im like seriously?!?!? and I gotta sit there like -_- , also the more i try to stop it the more the frequency of throbbing gets lmao. sorry for tmi but this is a yaoi smut site mostly so like who cares

Do you mean like feeling your blood pumping around there? Almost like you can feel your heartbeat? If so then yeah, that can happen. I call it a boner.
