The ruling on semen that comes out after the full ritual bath

The questioner:
May Allah reward you. This questioner says: Does the semen that comes out after the full ritual bath require a new full ritual bath, or does it invalidate the ablution?

The Shaykh:
What? The semen that comes out after the full ritual bath. It invalidates the ablution, yes. What comes out from the private parts invalidates the ablution, whether it is semen or not, yes.

The questioner:
Does it require repeating the full ritual bath?

The Shaykh:
No, unless he finds pleasure and a gush of it; then it is major ritual impurity and he must take a full ritual bath. But if it simply comes out without pleasure, then it only requires the ablution; he cleans himself and performs the ablution.
