How Does Having Mass Make It Less Likely to Interact?

Having mass makes it less likely to interact, or harder counteract. And also a shorter range, you can think of them as connected. Like imagine shooting two particles together and the probability of them interacting so depends on their relative distance. The fact that it's a shorter range force means it has a smaller cross section when the particles comein the other direction. Whereas if ye are using photons, they can fly everywhere.
