You just push your dick through the hole and move up and down. (Use a nice amount of lube.)

I have two [words=http://fleshlight.sjv.io/c/348327/302851/4702]FleshLights[/words], they're alright. A bit bulky and heavy, compared to other toys. They last long with good care, but there are "smaller" (yet good sized toys) available, that last pretty nicely as well.
I remember that there was a site comparing these [words=http://fleshlight.sjv.io/c/348327/302851/4702]FleshLights[/words], but it was in Finnish and I don't know was it published in other languanges. Very likely that it was. The Original [words=http://fleshlight.sjv.io/c/348327/302851/4702]FleshLight[/words] I wouldn't suggest, they've progressed for the better. More bumbs and details; more sensations.
I mainly rely on my hands and some lubricant. Lubricants also have different qualities. I kind of liked Gun Oil Stroke 29, but their silicone lube is also nice. I'm uncut by the way, but I really like the feeling a lubricant gives. Some see it might be more messy, but heck, I go for the feeling.
Tengas are kind of nice, but really more like a travel thing, they don't last long. (Some say only one use.) Tenga provides a longer lasting unit though, but that too has limited lifetime. But I think [words=http://fleshlight.sjv.io/c/348327/302851/4702]FleshLight[/words] will wear down eventually as well. Everything depends about the usage and how you maintain the unit.
Lots of nice toys out there. Just take time, relax and enjoy. Some toys are pretty much over stimulating, but with repeated use you can build up your [words=http://fleshlight.sjv.io/c/348327/302851/4702]stamina[/words].
A good exercise is to put your whole body work, not just your wrist. I'm quilty of just using my hands. Building up your [words=http://fleshlight.sjv.io/c/348327/302851/4702]stamina[/words] should simulate certain angles, body stress etc..
Sex will begin in your mind as it has been said.
