Yes, Mosques are public place, it's not just for prayers it's gathering place rather than prayer place, however some people like to have sex in public places but I can think of many public places that appropriate for such thing at least romantically.
Leave you with the story
Yahoo! News - NAIVASHA, Kenya (Reuters) - A couple caught having sex in a Kenyan mosque during the Muslim holy month of Ramadan have been sentenced to 18 months jail for what the judge called anabominableaffront to religion.
Peter Kimani and Jennifer Wairimu pleaded guilty to the charge of having sex in a place of worship after being caught on October 3 at the Abubakar mosque in Gilgil, about 60 miles north of Nairobi. Neither is a Muslim.
A worshipper heading for evening prayers found the couple having sex after investigating what the prosecution described as strange noises emanating from a dark corner of the mosque.
Kimani and Wairimu both pleaded for clemency at Monday's hearing, saying they were too drunk to know where they were. Kimani told the court he thought he was in a lodging house.
John King'ori, senior magistrate in nearby Naivasha, dismissed their plea.Having sex in a mosque is a most abominable thing to religion and only a custodial sentence can add justice to this,he said.
