Having offspring for gratifying feelings is socially induced, and this is also somewhat of a new phenomenon in the history of our species. It's only existed for much less than 0.1% of our time on the planet. Besides, if you didn't have a sex drive, you wouldn't be having children, either. The whole romantic connection is hormonally induced to keep the parents together long enough for the child to be able to function more independently so as to have a better chance to survive.
