Condoms are the only mean of contraception which prevents unwanted pregnancy and significantly decreases the chance of infecting with HIV/AIDS/STD.
If you care about your health, then always use a condom when having one night stand!!!
Condoms can’t be used if they have exceeded expiry date; their wrapping has been damaged; if they have dried out, too sticky or changed their color.
Efficiency of condoms if they are used correctly is 90-95%.
