This site has many women asking if they are pregnant or not. Many women believe that since their man used the withdrawal method that they cannot get pregnant. While I understand the reasoning behind this belief, the withdrawal method is NOT a reliable form of birth control and can in fact result in pregnancy.
Now as we all know, with a woman sexual arousal includes lubrication of the vagina. What many people do now know that men who are sexually aroused also become lubricated. The difference is that it is obvious with a woman, but virtually invisible with a man.
The inside of the penis must be lubricated in order for ejaculation to occur. Within this lubrication there are millions of sperm. Some people call this pre-ejaculate. The man is not aware of this happening in 99% of the occasions. So the vagina is exposed to pre-ejaculate and sperm.
THE PROS AND CONS OF WITHDRAWAL
PROS
Withdrawal can be used every time
Withdrawal may be added to other forms of birth control to increase effectiveness
Withdrawal is free
Withdrawal does not require a prescription or manipulation of a mechanism
CONS
Withdrawal is not considered a reliable form of birth control
The woman must have complete trust on the man’s ability to withdraw
Pre-ejaculation, which contains sperm, occurs without the knowledge of the man
Some men have difficulty timing their ejaculation and/or withdrawal.
So, if you ladies are experiencing any pregnancy symptoms and your man has been using the withdrawal method, please take a home pregnancy test or visit your doctor.
