Integrity and Houston are still discussing toilets, poo and wee-wee at the moment.

These are important things when you’re stuck on a small spaceship.

What happens when one of them lets go a ruddy great fart? Does it hang around til they get back and open the door?

The top of the suit, below the helmet, usually has a rubber ring that you have to squeeze your head through and that acts as a barrier. I believe it’s main reason is that so only the helmet has oxygen in it and not the rest of the suit as well.
The Soviet/Russian Orlan suits are very different, the entire back of the suit opens up so the cosmo/astronaut can get in & out and have the suit ready to go much faster than the US gear. The helmet doesn’t come off (I think) so no rubber barrier.
