What is Evidence not used in rape is and explain in detail?
In the uncircumcised penis the presence of smegma under the prepuce and on the corona glandis rules out complete penetration because smegma will be rubbed off during intercourse. Smegma usually requires 24 hours to redeposit. Presence of smegma indicates that no sexual intercourse with full penetration is taken place within 24 hours but absence of smegma will not indicate intercourse.
