Sorry it was hard to think of a good title.
Essentially, why do only virtual photons carry the electromagnetic force? What stops 'normal' photons from carrying the EM force? Is it the fact that we can detect them? What decides whether a photon will be virtual and hence carry the EM force, or is it vice versa that a prerequisite of carrying the EM force is being virtual?
