Sex

What have philosophers said about the idea that sex results in babies so therefor we should look at the meaning of any sexual act in terms of sexual reproduction? It does seem as if we didn't evolve to have sex without reproduction and therefor sex without reproduction is a modern phenomena not attached to our evolutionary nature. So maybe our emotional responses to sex and the feelings of shame that correspond with sex might be because of this evolutionary nature?
