Do you think it's possible people are overstimulated by easy access internet porn when alone to the point they aren't as interested in having sex when it's available with a partner?

Sometimes I think porn is addicting and keeps people in an ever escalating tither and other times I think it’s sapping the energy and attention away from couples time, especially for men who typically need a certain amount of time passed in order to “go another round”. Is porn getting the best?
