Vaginal expansion: The back wall of the vagina expands by about one third during sexual arousal to allow for "visitors that go bump in the dark of night". The action of intercourse often traps air inside the vagina which can be expelled at any time. This is very normal and should not make one forget why the "event" was ongoing in the first place.
