Pour a glass of wine, turn the lights down low, light some vanilla scented candles, turn on Brooklyn Nine-Nine and stick a ""vaginal dilator"" into your hoo-haw. Sounds like an enjoyable night? Well for our guest Molly it is quite painful. Vaginismus is a physical/mental condition causing extremely tight vaginal tissue making it nearly impossible for any sort of vaginal penetration. An issue, to say the least.
