Long term relationship, hyper active libido

First time poster here, I've looked at a few different avenues so I figured I'd give this a go, I'll try and keep this short....

In relationship for 15 years

married for 4

Recently had a kid.

I've always had a hyperactive libido, I could easily masturbate double figures during a day, if I had no plans.

I was fully prepared for the sex to stop given what pregency and childbirth does to a womansw mind and body.

However, 5 months later and nothing has resumed. I'm doing what I can to control my libido by self medicating (masturbating) but I'm growing more and more frustrated because every time I come home from work, I expect to see my wife all dolled up and ready to rock, but it never happens, I know she's got a lot on being a new mum so I try my best not to complain but a guy has needs.

Is there anything I can do to reduce my libido? Or increase hers?
