Poppers are good when you're watching porn having a wank, but as mentioned there's no need for them if you're balls deep in a wee hunny, there's a new type out now called penthyl, same kind of euphoria when you cum but it lasts a bit longer. If you're going to do anything like this to give yourself a better orgasm during sex I'd recommend either a wee blue helper or smoking a joint before you start, you get some tingle when you blow your load on weed.
