1) Why not? You only live once!
2) I think it's perfectly fine as long as emotions don't get in the way. Total no-strings-attached sex is fine.
3) My ideal 3some... hmmm... males: definitely Sean Biggerstaff (Oliver Wood from Harry Potter) and Gale Harold (Queer as Folk). Females: Angelina Jolie and Kirsten Dunst... don't ask why. I could probably think of a few other people but I'm too tired.
4) No. I believe that being sexually open is healthy. Not necessarily 'the more the merrier' but as long as some restraint and precautions are taken to ensure everyone is still mentally in tact afterwards it's fine.
5) I'm not bored. Who can resist a sex thread???
