Step 1: put toilet seat up (if applicable)
Step 2: feet shoulder width apart (if at toilet have shins/knees touching or right in front of bowl) with pants down far enough to allow that (down to knees for me)
Step 3: hook fingers on either side of tdick and pull back to the sides
Step 4: jut hips out forward a bit but not too far, kinda aim urethra with your fingers (hard to explain sry)
Step 5: piss. Adjust aim if necessary.
As with every unfamiliar stp method, I recommend trying in the shower until you have a good enough feel for it to not piss your pants or all over the floor.
