In my opinion it's best to stick to looking for knowledge in our own books rather than relying and aligning ourselves with the catholic kuffar whenever a modern issue comes up.
Saying it's common sense isn't good enough. Do children/kids/teens have enough common sense to decide what's right and what's wrong?
Introducing new stuff is bida and restricting yourself from what Allah(SAW) has allowed is also bida.
Catholics say masturbation is prohibited because of a story in the bible and that they are not allowed to "spill seed", we need something solid like this before we start using our "common sense".
Alot of people are out there using their common sense to worship at people's graves and doing sajda at peoples feet, if common sense was enough why would we need islam. Allah gave us a great nehmat in form of our beloved prophet (pbuh). People should appreciate what a great favour that was.
