Jesus knew that female children were being forced into wedlock with men and thus into the bedroom.  That is what marriage was in those days and this child rape was condoned on the grounds that babies were needed as people didn't live long enough to wait.  He banned a girl from divorcing her husband.  Female divorce did not happen but he was not going to take any chances. 

Gay sex in those days surely involved people doing it too young too.

The uncensored Gospel of Mark uncovered by Morton Smith suggests Jesus was interfering with a young man, neaniskos, whom he "raised" from the dead.

The word normally translated “youth” in the New Testament is neaniskos. Neaniskos is derived from the word neos, meaning “new” and usually means a youth or a young man.

In Acts 20, a neanias named Eutychus fell asleep during one of Paul’s long sermons. Bruce speculates, “Perhaps he had put in a hard day’s work from dawn to sunset, and now in the
stuffy atmosphere not even the words of an apostle could keep him from falling asleep.”

He fell from the third story window. It appears Eutychus was killed, and Paul raised the neanias from the dead (Acts 20:9). He is referred to as a child [paida] later in the story (Acts 20:12), so it seems likely Eutychus was young, perhaps a young teenager.

Mark wrote of a neaniskos who, on the night of Jesus’ arrest, followed Jesus clad only in a linen cloth. Some of the church fathers believed the neaniskos was Mark himself.

When soldiers grabbed him, the neaniskos lost the cloth and ran away naked (Mark 14:51). Lane suggests that the language Mark used “designates young men who are exceptionally strong and valiant, or faithful and wise.”  He identified this as a fulfillment of the prophecy in Amos 2:16: “And he who is stout of heart among the mighty shall flee away naked in that day” (ESV). Even the valiant young men were scattered the night of Jesus’ arrest.

Paul uses a form of the word when he warns Timothy to “flee youthful [neōterikos] passions and pursue righteousness, faith, love, and peace . . .” (2 Tim 2:22). Mounce believes that
while “youthful passions” could include “the sensual lusts of youth,” the context better fits a “youthful temperament and the possible difficulty of avoiding arguments.”  Such issues seem
more easily associated with “faith, love, and peace” (2 Tim 2:22).John offers insight into the role and expectations of the neaniskos when he addresses the church as children, fathers, and young men in 1 John 2, I am writing to you, little children, because your sins are forgiven for his name’s sake. I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men [neaniskoi], because you have overcome the evil one. I write to you, children, because you know the Father. I write to you, fathers, because you know him who is from the beginning. I write to you, young men [neaniskoi], because you are strong, and the word of God abides in you, and you have overcome the evil one. (1 John 2:12–14).

Twice John repeated that the neaniskoi have “overcome the evil one” (vv. 13, 14). He casts the young men as warriors. Because they are forgiven, they can overcome the devil. Stott
writes, “The forgiveness of past sins must be followed by deliverance from sin’s present power, justification by sanctification. So in both messages to the young men it is asserted that they have overcome the evil one. Their conflict has become a conquest.”

In verse 14, John explains why the neaniskoi have overcome: they are “strong,” and “the word of God abides” in them (1 John 2:14). Kruse indicates that the reason they are strong is
because the word of God dwells in them.  He writes, “Believers’ victory over the evil one [is] achieved because God himself abides in them and his Son, Jesus Christ, protects them, and as a result they are able to overcome the evil one through their faith in God.”

Paul told Timothy, “Let no one despise you for your youth".

It is clear that we are talking about very young men here and possibly boys.  The gospels say that the apostles kept children away from Jesus for the sake of peace.  Jesus objected.  What if the concern was something else?
