Talk to your wives. Work on the relationship, fix the relationship.
Help out at home n take care of the kids.
Continue to do romantic things
Daily sincere acts of love assurance and appreciation matters

When having sex, the importance of your wife enjoyment is key to constantly getting more sex.

Get yourself tied or she IUD so no more stress over another kid. Unlimited creampie stress free

Go to the gym, work out and dont be a fat lazy fuck

Have a life. Dont just work and go home watch tv , drink beer or play games
For example, photography, cooking, fishing, cycling, and many more.

Ask yourself if you would fuck yourself before wondering why ur no longer getting sex.

Keep improving yourself.

Lastly
Dont validate your enjoyment of life, worth and happiness base on sex.
