I’ve got a question- my boyfriend just got a sperm analysis and although theyre healthy, they are really really few.

We do not currently want a child and the doctor said that in the future, things can be done to have a child. However, my question is whether in that case it is alright for him to cum inside me? I’ve always been scared to allow him to do so as we are not financially ready to have a kid yet. But since the doctor says there’s an extremely low chance of him impregnating me and I am on the pill, would it be safe for him to cum inside?
