where to put the lubrication?

I thought I read some where that one should not put the lube on the penis but outside on the condom. Becase if you put the lube on penis condom might slip. But based on the following one should put lube on the penis as well. Not sure which approch is recommended.


"
Generously apply a water-based lubricant to your penis (or to the inside of the condom) before putting the condom on. (This allows the penis to move around slightly within the condom.) Once the condom is securely in place, rub lubricant on its outer surface, then apply more of the lubricant to your partner's vagina or anus. During sex, rub on more lubricant at frequent intervals. Keeping everything well-lubed cuts down on friction and puts less strain on the condom, making it even less likely that the condom will tear."
