Trying to find the name of a sitcom I was too young to watch but snuck up and watched anyway from the 90's. Was on HBO potentially cinemax. Was about a very wealthy family was kind of like Married with children but much more adult. The father had a mistress the wife I don't recall much about and there was the stereotypical daughter and really weird son. The only episode I recall was centered around the son's experiencing priapism and it ended with them going to the ER to handle it.
