Whenever I'm tempted to think of the "good" in the Family which isn't often I just remember living in the East where all the adults in a huge Home would have sex in the swimming pools. Then families with little children would swim in them & the kids would get herpes sores in their eyes & their armpits. You'd get sperm in your hair too.
Even if they had sex in their beds, Grandpa's rules were you didn't use the shower. To conserve water you had to wash off all that sperm & sexual juices in the pool. And then in the morning when the brother in charge of the pool went out to skim off the leaves he couldn't for the life of him figure out why the pool was covered with a white film.
No one could figure it out. So the kids kept getting sick with all kinds of infections & sores until finally one bright person clued in & a ban was put on pool sex.
Of course, Grandpa made sure we still shampooed our hair in the pools & of course all the daily baths were in the pools, which meant that the soap often got forgotten in the pool and clogged up the filter.
