Sex with wife feels like a chore

Me(45) and wife (41) have been married for 5 years and been together for 9 years. We recently had our first kid about 10 months ago. I love her dearly but I am having intimacy issues, and really have a hard time getting in the mood to have sex with her, it feels like a chore to me especially pretending that I am interested.

I don't know if I can say exactly what my problem is or it may be multiple things working against me.

I'm not physically attracted to her body after what the pregnancy and birth did to her body, I understand that's out of her control and don't want to make her feel like she's ugly in anyway, so I've never brought it up.

When we do have sex, shes extremely sensitive and I feel like I can't do anything to her without her saying 'too much'. We haven't had intercourse in a year because of that and all intimate encounters are of the oral kind (I still have to be extremely gentle). And I'm bored, we follow the same exact script every time and it's just feeling like I'm going through the motions.

What can I do to save my marriage? I know the lack of intimacy is effecting her and want to figure something out before it becomes something bigger. Any advice would be appreciated.
