I usually burn the image of the hottest passenger/flight attendant in my mind and masturbate multiple times during long flights. I typically stand with my heels touching the door to prevent anyone from opening it, and I lean at about a 45 degree angle toward the toilet. I then use one hand to keep myself steady while using the other to masturbate. If there is a mirror I usually look at it and admire the size of my erect penis while I masturbate as well. I find that doing this helps me sleep better.
