Are ballgags usually latex? Some people have a sensitivity to latex which could be problematic. Silicone rubber would be preferable if it were an option as it is hypoallergenic and would stand up better to wear and tear and a little sterilising perhaps as saliva is loaded with bacteria and can produce some rather unpleasant odours if left to incubate somewhere warm, the smell will be worse if the saliva donor had recently eaten something meaty... (no seriously, I mean 'eat' as in a proper meal). I guess alcohol wipes would be useful.
