Depends: Proper use of condoms require that they be applied before any intercourse, fit well & be replaced for any new session. When this is done, likelihood of pregnancy is minimal. Semen is produced by the excited penis continuously & contains enough sperm to cause pregnancy.As long as there is never any possibility that semen reaches your genitals you are safe.
