lubricant

Lubricant can be used to avoid breaking a condom during vaginal or anal sex. To be compatible with condoms, it should be mentioned on the lubricant, usually water based or silicone based. It may be better than saliva but has to be renewed also. However if you are only looking for casual hookups, it is better that a woman chooses a lubricant that she tried alone first, since some people have allergic reactions (even with organic lubricant) and guys could lose the opportunity to get laid if it happens!
