Concerned that now I’m pregnant my boyfriend is watching porn

My boyfriend and I typically usually have sex every other day.

Since I’ve gotten pregnant whenever we have sex he can’t cum...

I know this isn’t a physical problem he definitely can cum I’m just worried that he’s Cummins g by himself now.

He works from home and locks his door which I find weird and I heard him jerking off in the shower last night.

This is giving me so much anxiety. I feel like it’s the same as cheating. I don’t know how to talk to him about it.
