John Lloyd Cruz, Shaina Magdayao and the Vaginal Lock Rumor?

John Lloyd Cruz and Shaina Magdayao experienced a vaginal lock, thus forcing them to seek medical attention at St. Luke’s Medical Center?

Per unverified sources, Shaina Magdayao suffered from vaginal captivus, wherein the vaginal opening of a woman closes, perhaps due to fatigue. Anonymous people claim that John Lloyd Cruz and Shaina  Magdayao were having sex in the latter’s house. Shaina’s vaginal opening apparently locked while John Lloyd’s genital was inside it. What they did was to cover themselves with a blanket and rush to the St. Luke’s Medical Center.

What do you think really happened or did this really happened?
