Africa has the highest number of AIDS victims in the world it is not a safe anywhere.
Don't think it is an easy job, not every man can work as a porn actor and a rare woman will agree for this. If you think you're good enough for this you can try webcams, many famous actors promoted themselves as amateurs (at sites like http://www.asiansexed.com/ ). If you succeed in this, you can send your CV with videos attached to famous studios and porn producers.
Good luck!
