I love my fleshlight. After I've pumped nice and thick and use the fleshlight, the orgasm sensations are even more spectacular, especially with the extra sensitive feeling in the area right below the glans.
I have all of the different types of fleshlight inserts. My favorite one is the "speed bump". If I've pumped first and then use my fleshlight, it's very difficult for me to hold off from cumming. It feels just so great.
