Outercourse

Effectiveness: 100%

Sexual contact without vaginal penetration. It works by keeping sperm separate from the egg.

 

Availability: Anyone
 

Cause of Failures: Semen comes into contact with the vulva or vagina.
 

STI Prevention:

  • Prevents STIs unless body fluids are exchanged during oral or anal intercourse.
  • STIs spread through skin-to-skin contact (like HPV, herpes and crabs) may be spread through outercourse.
  • Condoms make good barriers for oral sex on a penis.
  • Dental dams or condoms cut lengthwise and place over the vulva are good barriers for oral sex.
