I have the ability to become sexually aroused, and reach the point before climax, but when i am almost there my vulva area has intense discomfort. It feels like a painful numbness, and is immediately too uncomfortable to touch, therefore i have never reached orgasm as the arousal stops very quickly after this. It's very annoying as i have the desire and arousal just not the final end point, it always painfully trails off.
I have read a few articles about internal pain, but mine is definitely the external parts of the vagina.
I have never given birth, and am under 25. I am on a combined birth control pill. I am suspicious that it could be hormone levels, or the rush of blood being what is painful, but i am unsure. Has anyone got any similar experiences, or an idea of what is wrong, and ways to help this issue out?
