Am I wrong to be upset?

My husband jacks off every single day most of the time twice a day on top of us having sex. He’ll get off in the morning we’ll have sex later then he still gets off in the evening before bed every single day. He always closes down the screen on his phone if I come into the room but swears it’s me he’s looking at. If its my pictures why does he feel the need to hide it? I don’t care that he gets off I don’t even care if he watches porn but when it’s every day twice a day... I feel like he’s not getting the satisfaction he needs from me and yes I have talked to him he gets defensive and shuts the conversation down. I feel like I’m never going to get pregnant because he’s always cumming and that can’t be doing good things to his sperm quality.
