Welcome to the future
The other night I saw an episode of 'That 70's Show' where Red and Kitty's daughter moved in guy before marrying him. That was a really big deal at the time with older generations. My dad's mum found out that my parents lived together before getting married and didn't speak to them for like 2 years because of it. She thought my mum was a massive ****. And now we're in 2015, where romantic comedies start with people being ****-buddies (Friends With Benefits, No Strings Attached) and internet hook-ups (Two Night Stand).
Each generation is just going to be more sexually liberated than the generation before them. This isn't anything new. It's good. It's healthy. It'll prevent more people from marrying the wrong person and wasting their whole lives with them.
Liberals want to liberate us into the future while conservatives want to conserve traditional values. There's nothing wrong with sex.
