Condoms

If condoms are habitually breaking on you, odds are that you're not lubing them up enough. Just a couple drops rubbed around on the condom works WONDERS. Some ladies even dab themselves before insertion. It might be me, but it seems that condoms aren't as wet these days as they used to be. Back in the day the moisture was almost dripping off the condom as soon as you unrolled it. Nowadays it seems like there's just enough lube on it to make it functional. Nothing...NOTHING kills a session like a rapidly fading condom (especially if it's the last one). That's why it's always good to have some reinforcements (lube and extra condoms).

And make sure it's water-based.
