What is the name of the transparent, viscous fluid that is discharged after sexual intercourse and continues intermittently for two hours or more, and does it nullify ablution?

The described characteristic is most akin to the characteristic of madhy (pre-seminal fluid), which is a viscous fluid that usually exits after sexual arousal or after the emission of maniy (semen). Its discharge is natural, not gushing, and often exits intermittently. Wudu' (ablution) is required from it, as is washing the penis and whatever of the body or clothes it touched. Prayer is not valid until after that. It is not considered a case of incontinence unless its discharge is continuous all the time.
