Andy is now married and he and his husband are expecting their second child with a surrogate next month.
He said he understood the challenges that can be faced by young people as they come to terms with their sexuality and identity.
“It’s the one thing I thought when I first watched Heartstopper, and I’ve heard it many, many times since, especially from people sort of my age really, about how they wish they’d had a show like this when they were growing up,” he said.
“Just knowing that there are other people out there, that queer people exist, and that queer love is possible, and family life within that sort of relationship is possible.
“Hopefully, shows like this will make it easier for the next generation coming through… to hopefully accept themselves a bit more easily and a bit quicker, and maybe some of that shame won’t exist in the same way like it did for a lot of us.”
