Jerk off everyday

My husband jerks off to porn everyday. We can have sex at night and I get woken up to him jerking off in our bed in the morning to porn. Or I come downstairs after he left for work and find his sperm papertowel. I am sick of it. Every time I get woken by the bed shaking or find evidence I feel cheated on and not enough. I feel sick. Is this normal behavior for men?
