Why do so many songs refence sex?

Is it just me or do songs like 'Juno' (sabrina carpenter) gross me out? I still like people in a relationship but not sex, and the song is all fine until 'your dad's genetics' and 'try out some freaky positions (have u ever tried... this one)' and A LOT other songs like that. I don't see why people can't make a love song without mentioning/referencing sex? It's weird.

Not saying I hate the songs, some are my favorite, but I'm just saying its weird
