My brother is 26 and his gf is a similar age. Because we're on the other side of the world they've a long distance relationship but he traveled there last year to spend a few months with her. They talk basically all day on a Saturday and Sunday as he works during the week. There's nothing creepy or pedophilic about him yet that's clearly the assumption that would get made when despite being around the same age. And yes I have seen what his gf looks like and she speaks to the rest of the family sometimes too.
