IUD and no pull out?

So I just got my IUD placed on the 8th so I would have a better form of birth control and also so me and boyfriend can have condomless sex. My boyfriend keeps asking me if I think it would be safe for him to cum inside me instead of pulling out and honestly I’m not sure. Does the IUD work well enough to have sex without a condom or pull out method?
