Daniel Radcliffe admitted that he is quite bad at romance and didn’t know what to do when he started dating his current girlfriend.

The actor met girlfriend Rosie Coker a year ago, on the sets of Harry Potter where she was a production assistant.
“I hated dating because I’m crap at it,” the Daily Mail quoted Radcliffe as telling Parade magazine.
“With Rosie, I didn’t know what was appropriate, like on which date you’re supposed to try and kiss her,” he said.
He made a dating faux pas on his second date itself, and credits Coker’s sense of humour for the fact that they are still together.
“At the end of the second date I pulled a move out of the Bela Lugosi Book of Woo, I went to kiss Rosie and at the last minute lost my nerve and ended up kissing her neck, which is such a weirdly intimate place to kiss somebody on a second date,” he said."Afterward, I texted her, saying, ‘I’m sorry, what I just did probably seems very odd to you’ fortunately, she just found it really funny, so she kept coming back," he added.
