I still haven't seen where it was said that the person was a "boy". Not doubting it, but haven't seen it.

From the linked article:

The four claims made against the presenter

It's been five days since the Sun published its first story about the BBC presenter.

Here's a quick summary of the four sets of allegations:

• On Friday, the Sun's first story is published about the mother's claims that a BBC presenter paid their child tens of thousands of pounds for explicit photos over three years. The paper quoted the mother as saying the young person used the money to fund a crack cocaine habit, and that she was worried her child could "wind up dead". The lawyer representing the young person has since disputed the allegations, describing them as rubbish".
• On Tuesday afternoon, the BBC reports that a second young person had made allegations claiming the presenter pressured them to meet up and then sent abusive messages when they hinted at revealing their identity
• Last night, the Sun reports fresh claims from a 23-year-old who claimed that the presenter broke lockdown rules to meet them during the pandemic in February 2021 and sent them cash
• Separately, the Sun publishes messages allegedly sent to a 17-year-old after a conversation was initiated on Instagram in October 2018

No mention of boy, man, just young person.

Also, even if it is a man I'm not seeing the homophobia, just sounds like a factual statement. They are or they aren't.

I only heard 'young person' on the coverage
