London, March 22 (IANS) Robert Pattinson says after doing sex scenes with Emilie de Ravin in 'Remember Me', he has a newfound respect for porn stars.

'When you end up doing it, you have this little patch on your privates. I didn't really tape it up properly, so I'd spent so long taping it round myself and then literally it falls off within one second and it's taped to the sheet. And you realise the whole crew is looking directly at your butt crack. I can't think of anything exciting for them about this. It gives you a lot of respect for porn stars,' contactmusic.com quoted him as saying.

While shooting Pattinson was uncomfortable.

'Emilie was very, very, very comfortable. I'm always the one who's the most uncomfortable. So we came into the room, and they said 'It's a closed set,' blah, blah, and we got on to the bed and the director was like, 'I got you these things, if just maybe you wanted to use them. You don't have to use them, maybe it will make you more comfortable.' They were these bondage things: lube and handcuffs and porn videos. It was so funny!' he added.
