Do condoms work?
<|assistant|>
Yes, condoms are effective at preventing pregnancy and most sexually transmitted diseases when used properly. Proper usage includes making sure the condom is the right size, using the condom consistently and entirely, avoiding simultaneous sexual contact with other partners, and not using multiple condoms for a single act of intercourse.
