Sex after pregnancy

So I’ve been really worrying about this... so after we have the baby... I know you can’t have sex right away but once we can I don’t want to use condoms because they give me an infection and I want him to cum in me so I feel closer to him... i was on the patch for 4 years and never used condoms and never got pregnant until I took it off and a year of trying. How long should I have my birth control on so it’s really effective because I don’t want another baby for a couple years ??
