No sex but he’s masturbating …

help ! Sooo my husband DOESNT have sex with me anymore . I’m lucky if I get it maybe once a week. Last time we had sex was last Friday & the time before that?? Idk . And sometimes when we have sex he has to watch porn to finish . I didn’t think I was that horrible 😞 I ask him if it’s different since after the baby … he said no he just wants to keep our sex life alive and not get bored …. Ok???? So anyways , he hopped in the shower right now and I heard him masturbating to porn . Do I bring it up to him??? Why can’t he have sex with me ? I literally tell him all the time idc if he masturbates , as long as I’m still getting some too.. but I’m not . Do I confront him? Or is that embarrassing
