I think you really misunderstood Apostle Paul on his view regarding staying single and getting married. I think its best to read and digest what an ancient Apostle said and meant before concluding or judging them on what The Lord put in their mouth.
7 I wish that all of you were as I am. But each of you has your own gift from God; one has this gift, another has that.
('I WISH' is not a command. I could turn to my friend and tell her that I wish she could sing or act like me, it does not mean I will make her or command her to. Apostle Paul wished because he was happy being a single man. He knew he could not be tempted by the enemy to fornicate or have immoral sex. That is why he pointed out that everyone has their own gift from God. No man is the same. Some men are happy to be monks and some are happy married. That is how God designed each person)
8 Now to the unmarried[a] and the widows I say: It is good for them to stay unmarried, as I do.
(It is good does not mean a command. Its an advice to the people being spoken to. For all we know, they were all committing adultery even while married, and doing all sorts of things which were sins unto God)
9 But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion.
(And this concludes his message which really does emphasise what he was going on about. If you can't control yourself, MARRY...whats the point of burning with passion and committing immoral acts. Better to marry than burn with passion. So in conclusion, aPOSTLE paul did not encourage anyone to not marry neither did he command or force them. God has the final say in everything, and none of the apostles claimed to be God or acted like one. They only did what The Lord sent them to do.)
