A condom is a type of birth control method that prevents pregnancy and sexually transmitted diseases. They are worn over the penis while indulging in a sexual activity like intercourse. Condoms act as a barrier which obstructs the flow of semen from getting into the vagina. Condoms prevent the viruses from spreading from one person to another. A condom can prevent pregnancy up to 97% if used regularly and properly. Practically speaking there are no dangers if a condom is used effectively and properly. A few men cannot withstand their erection while using a condom which may result for the condom to slip of the penis. Having intercourse with a condom that has been used once can be very dangerous. It’s never safe to use expired condoms as condoms with an expired date can tear a lot more easily which involves a lot of risk, so better be aware and check their expiry date before buying one. There are no dangers associated with the use of a condom if used effectively but it can be dangerous for not using one. By using them you prevent the diseases, protect yourself and your partner.
