Usually I go until I'm about to cum (edge) and then slow down a lot.. and then I can last a while once the feeling dissipates

But, i'm looking for ways to train my body to last longer.. anybody have tips?

I want to be able to go at it rough for a good 5 minutes, but I usually can't.. and have to slow down/intentionally take it out and do other things or i'll blow my load.
