When someone needs assistance with penetrating their partner.
Predominantly used by blind, poor sighted people or those with an obese partner where finding the correct hole is extremely difficult - guided entry is needed.
Can also become necessary when trying to penetrate with a semi-on. See "Thumbing it in"

Geoff "no, she gave me the guided entry"
