Where does Paul say he's celibate? It's one of the many lies Christians tell-- that being "unmarried" means sexual abstention.

Jewish law doesn't regulate the sexual expressions of single people. Samson sees a prostitute in Judges 16:1-3, no problem. Abraham has sex slaves, etc etc.

All Paul says in 1 Cor 7 is that he's unmarried, i.e. not devoted to a home life focused around reproductivity, property management and local influence-building. He wishes this for all people.
