The 23-year-old actor said that he frequently gets sent “worrying” messages full of Harry Potter-related innuendos.
He told UK newspaper Daily Star Sunday: 'The fans love nothing more than a Potter innuendo. JK Rowling doesn't realise it happens, but they're all at it.
'There seems to be a non-stop list of dirty takes on stuff from the books – all about wands and broomsticks.
'I wrote on Twitter I was going to bed and a fan messages asking, 'Can I Slytherin?' That was so witty I almost replied.”
He added: 'I get some bizarre requests from fans – worrying stuff. One asked for underwear and others seriously ask to marry me. I think that's a bit forward.'
