No one should be without a good lubricant. Used for intercourse, masturbation or sex toy play, lubricants are the most important part of sex. Look for a good lube that will last long and not get sticky. You will basically find 2 types of lubes here. Water based and silicon based lubricants. Silicone based lubricants will last longer but cannot be used with silicon based sex toys (true skin, cyberskin etc ..) or silicon based condoms. Water based lubes can be used anywhere with anything, but you may have to use a bit more. It's your call.
