Do I have to tell my FWB if I hook up with another guy?

It's understood that we're not dating/exclusive but I hook up with my friend all the time when I'm home and we do everything even . We care about each other but just don't want to date since we're at different colleges. We're allowed to have with other people when we're off at school, but do I have to tell the friend with benefits if I happen to do that?
