Dr John Dean, a senior UK-based sexual physician, says that both accounts are credible examples of a rare phenomenon that doctors sometimes call "penis captivus" (captive penis).
"When the penis is in the vagina it becomes increasingly engorged," he says, giving his hypothesis of what causes the problem.
"The muscles of the woman's pelvic floor contract rhythmically at orgasm. While those muscles contract the penis becomes stuck and further engorged."
Finally the vaginal muscles relax, the blood flows out of the penis and the man can withdraw.
