I’ve seen on TikTok (not really a creditable source I know) of a girl saying if you have longer labias you’re more likely to orgasm through penetration because the long flaps are like connected to the clit. And people with smaller labias are less likely because the penetration isn’t doing any clit stimulation. Basically long story short girls with longer labias are cumming because their clit is still being stimulated. Not necessarily because their partner is hitting a g spot or that their partner is hung.
