In the Jewish culture that Paul grew up in it was expected that every male would be married by their mid-twenties. Paul says he was a Pharisee and the son of a Pharisee. It would be extremely unlikely that Paul's father had not arranged a marriage for him.
Paul plainly states (Acts 22:3; Phil 3:4-6; and especially Gal
1:13-14) that he followed the traditions of his people
Many believe Paul, [Saul], was a member of the Sanhedrin. To be a member a man had to be married.
I have read that in 1 Cor 7:8 Paul classifies himself with people who were previously married. I am not a Greek scholar and will have to let others discuss the Greek word Paul uses.
I've heard it preached along these lines, and generally agree. Whether Paul was ever a member of the Sanhedrin or not is not known, but it appears he was well on his way to be. Was he not, as Saul, carrying out the orders of the Sanhedrin in persecuting the Church?
I personally believe he may have been a widower.

There is scriptural support for the notion that
this 'thorn in the flesh' was most likely a speech impediment (like Moses), and not bad eyesight.
And by reason of the exceeding greatness of the revelations,
that I should not be exalted overmuch, there was given to me a thorn in the flesh, a messenger of Satan to buffet me,
that I should not be exalted overmuch. 2 Cor 12:7
For Christ sent me not to baptize, but to preach the gospel:
not in wisdom of words, lest the cross of Christ should be made void. 1 Cor 1:17
1 And I, brethren, when I came unto you, came
not with excellency of speech or of wisdom, proclaiming to you the testimony of God.
3 And I was with you in weakness, and in fear, and in much trembling.
4 And
my speech and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power:
13 Which things also we speak,
not in words which man`s wisdom teacheth, but which the Spirit teacheth; combining spiritual things with spiritual words. 1 Cor 2
For, His letters, they say, are weighty and strong; but his bodily presence is weak, and
his speech of no account. 2 Cor 10:10
But
though I be rude in speech, yet am I not in knowledge; nay, in every way have we made this manifest unto you in all things. 2 Cor 11:6
