Live cam girls - free vs paid for

Yesterday morning after my husband left for work I got into the shower. I immediately saw that in the actual shower, on the caddy, he had forgotten his phone. I’m not stupid and I knew he was probably masturbating in the shower. We have a 15 month old and I’m currently 3 months pregnant, so I wasn’t surprised or upset since my sex drive has been low and it’s uncomfortable to have sex. We have sex twice a week currently. Anyway, I don’t go through his phone, but I was curious because it was in the shower of all places and so I just opened up the page he had been on and it opened up to a live stream of a girl masturbating. The page said it was a free cam girls site, so I guess you don’t have to pay, I don’t know. When he got home I asked him if he was watching live girls on cam and he said yes. I didn’t say anything after that because I thought whatever. But obviously it’s been on my mind ONLY because it’s a live stream. I don’t know. I know he watched porn occasionally and again, whatever, but live cam girls seem weird to me. Am I wrong to feel weird? Should it only be a big deal if he has paid? I would like some insight. ❤️
