It have the exact same thing happen. It hurts sooo bad for like a few days after. My boyfriend is also super clean. Takes 2 showers a day and cyts his nails daily. Idk what the problem is and its only this one guy. Ive been fingered by 3 other guys and its never hurt.
you could have a yeast infection or some sort of infection. or he could have fingered you too hard and made a tear in there, I've had that happen and it hurts for days , even to the point where you sit down it hurts, but they have cream for that hope your ok
well he is actually really clean, so idk.
He could have skin bacteria that irritates you. How is his hygiene? Clean hands and nails? I'd stop letting him finger you, frankly. It's not worth the risk of getting some kind of fungus or bacteria in your vagina.
