Unprotected sex
From Free net encyclopedia
Unprotected sex refers to any act of sexual intercourse in which the participants use no forms of protection from sexually transmitted diseases. It can thus be contrasted with "safe sex".
Less commonly, it is used to refer to sexual intercourse without the use of any form of contraception.
The two meanings are different because there are forms of contraception that do not involve barrier protection such as the oral contraceptive pill.
