i am a 25 years old, i had sex with my boyfriend but my vagina was just dry, he tried so hard to do foreplay and make me wet but it did not help, he penetrate and after sex i felt like my vagina was burning, two hours later when i woke up, i feel like i am swollen or having stone inside the abdomain, now it is 8 hours past but the pain is still the same. It is my first time experiencing this and i am worried, what could it be?
