Personal lubricants (colloquially termed lube) are specialized lubricants used during sexual acts, such as intercourse and masturbation, to reduce friction to or between the penis and vagina, anus or other body parts, or applied to sex toys to reduce friction or to ease penetration.
Surgical or medical lubricants or gels, which are similar to personal lubricants but not usually referred to or labelled as "personal" lubricants, may be used for medical purposes such as speculum insertion or introduction of a catheter. The primary difference between personal lubricants and surgical lubricants is that surgical lubricants are thicker, sterile gels, typically containing a bacteriostatic agent.
