I know there's a lot of people on these forums with fleshlights, well I just thought I'd share my methods for the most practical use. I've had only one fleshlight and it's lasted me many years, though there are many other masturbation sleeves out there that some find even better I would like to try personally.
First off, for the the first couple of years I used to heat my fleshlight up for 15 mins in warm water, now I don't bother anymore because my penis heats it up anyways and in my average 2 hour sessions having it warm for the first 5 mins doesnt really matter.
The most important tip, I think, is using your fleshlight without the case. It allows for more dexterity. When you want a lot of suction you can just create it manually.
When you're done and you finally cum in it, leave your penis in the fleshlight and scrunch up the fleshlight so your penis pushes out all of the cum. This makes cleaning easier and you can see how much you came.
To clean it just rinse with water, and once a month pour a tiny bit of rubbing alcohol inside of it. You can also use corn starch every so often to keep it soft, but this isn't really necessary.
Now, what's going to make cleaning easiest is if you have some kind of small and thin rod, other than your penis. Wrap a very thin washcloth or other fabric around the rod and stick it in your fleshlight to dry the inside. Just wrap it up in a towel and leave it somewhere to dry. There's hardly any effort at all involved.
Well, this is the end of my guide, good luck with all your fleshlight goals in 2011.
