Should he really pull out?

I'm married, and so I have sex with just one person and am not worried about STIs or whatever, but if I'm on the pill already, what's the point of having a condom as well or pulling out? I see a lot of women get the advice to glove it AND take the pill, but as someone who's married, is this really necessary? Can't I just switch over to solely using condoms/the pill and be protected from pregnancy?
