Most condoms are made of latex, which is a type of rubber. Condoms come in all sizes, colours and flavours. Most are covered with a lubricant to make sexual intercourse easier. For those who have a latex allergy, there are also latex-free condoms. A condom may reduce sensitivity a bit, which may be an advantage as it can prolong intercourse.
Sexually transmitted infections
Condoms are the only form of contraception that protects against both pregnancy and sexually transmitted infections, such as chlamydia. Studies indicate that your partner will view you as a responsible, caring adult if you suggest using a condom.
