Also, pulling out is very effective.
Pre-ejaculatory fluids carry both sperm and disease. Coitus interuptus involves little planning and comes with one simple instruction: pull and pray.
As much as orgasms can be predicted, sometimes they sneak up on you. Even if you are able to pull out in time, it still puts you in the danger zone.
Pulling out does not prevent you or your partner from contracting a venereal disease and it' s not a reliable way to protect against pregnancy. The pull and pray technique isn' t a valid method of contraception and it should not be used!
