Husband would rather masturbate than have sex with me

Okay you guys. I need advice from someone who has been married longer than me. And I've only been married 2 years so probably most of you lol. I literally have no one to talk to about this cause none of my friends are married or even in relationships. And it's gonna be tmi so if you are shy about this stuff go ahead and skip this now lol. So I may totally be overreacting. But last night, I asked my husband if he wanted to have sex and he said no, that he was too tired. But he proceeded to stay up till 5am playing video games with his guy friends online so he wasn't too tired for that. Then this morning he hands the baby off to me and tells me he's going to take a shower. Well a few minutes later I go to the bathroom to pee and the door is locked. Then I hear him masturbating to porn in the bathroom. I am all shocked and grossed out (mind you, I truly don't care if he watches porn or takes care of himself in that way. I'm totally okay with it, but he was doing that instead of with me when I offered twice while the baby was asleep. And he was just going at it while I was sitting in the next room). So anyway, he comes out and I was all pissed so I made only enough coffee for me and he was like "hey what gives?" So I'm like why'd you take so long in he shower? And he flat out lied to my face. He was all "idk I just zoned out thinking about work. I didn't think I was in there that long." And so I told him what I heard and he lied again! When he finally knew he was caught he fessed up but he was totally okay with lying to me. What would you all do in this scenario. I understand he wasn't physically cheating, but the sneaking and lying is what really got to me.
