"Police said it was because they were seen having sex in public on the balcony of their ship cabin"

It's always about sexual display for people who have this ailment! 

Indeed, it seems reasonable that people who suffer from one mental illness may suffer from an additional one as well, such as a desire to perform acts of sodomy in public.  It seems to happen a lot with this bunch.

Indulgence in one leads to others.
