1 Corinthians 9:5

9:5 Do we not have the right to the company of a believing wife, like the other apostles and the Lord’s brothers and Cephas?

1 Corinthians 9:1

The Rights of an Apostle

9:1 Am I not free? Am I not an apostle? Have I not seen Jesus our Lord? Are you not my work in the Lord?

1 Corinthians 3:2

3:2 I fed you milk, not solid food, for you were not yet ready. In fact, you are still not ready,

1 Corinthians 4:3

4:3 So for me, it is a minor matter that I am judged by you or by any human court. In fact, I do not even judge myself.

Hebrews 13:4

13:4 Marriage must be honored among all and the marriage bed kept undefiled, for God will judge sexually immoral people and adulterers.

sn Milk refers figuratively to basic or elementary Christian teaching. Paul’s point was that the Corinthian believers he was writing to here were not mature enough to receive more advanced teaching. This was not a problem at the time, when they were recent converts, but the problem now is that they are still not ready.
