I have been a flight attendant for over 12 years and I never leave home without my enema gear in my cabin bag. Many of the flights involve an overnight in a hotel somewhere and the first thing I do wen getting into my room is to fill the bathtub with nice warm water Fill my enema bag and lay back in the tub and insert the nozzle and allow the water to fill me slowly. When filled I jump out onto the John and empty out before getting back into the tub and filling again. Some days I repeat this process about 4 times.
Another alternative is to take the Higginson into the tub with me and , relax and slowly pump the water in. (at this stage I havnt managed to empty the bathtub LOL )
I have carried my enema equipment for the 12 plus years and never been inspected by a customs officer. I wouldnt care any way Im not ashamed of having regular enemas, its my prime source of pleasure when away from home
Love Sally
