Muttley - I have a sensible answer.
[casts a disdainful eye around the thread]
Station a broom, or other long-handled househole implement (carpet-sweeper?) next to the toilet. When you lift the seat, simply pull the broomhandle across, diagonally, so that it props the seat up.
Perform, return broomhandle to upright position, return seat (and lid) to closed position, flush, and wash hands.
As you are both blokes, the final four instructions may be disregarded.
