What condoms should you use for anal intercourse?

With anal intercourse more strain is placed on the condom. You can use stronger condoms (which are thicker) but standard condoms are just as effective as long as they are used correctly with plenty of lubricant. Condoms with a lubricant containing Nonoxynol 9 should NOT be used for anal sex as Nonoxynol 9 damages the lining of the rectum increasing the risk of HIV and other STD transmission.
