London, April 18 : "Harry Potter" actor Rupert Grint admits that it was 'nerve-wracking' experience filming his first sex scene for his new movie "Cherrybomb".

The actor already had an on-screen kiss in "Harry Potter and the Half Blood Prince", but says getting intimate in new movie "Cherrybomb" was a lot harder, reports contactmusic. com.

"In 'Harry Potter' it was just a kiss. It was suggestive more than anything. This was a lot more intimate. It was quite nerve-wracking. I was quite nervous about it," said Grint.

Although he got his top off for the scenes, Grint doesn't think he could follow in his "Harry Potter" co-star Daniel Radcliffe's footsteps and strip off completely for the Broadway play "Equus".

"I don't think I could. Just being on stage would be quite a scary thing, let alone with no clothes on. It takes a lot of courage," said Grint. (IANS)
