How dangerous is it to have sex without a condom?

Having sex without a condom increases your risk of sexually transmitted diseases (STDs).  You never really know if a person has an STD just by looking at that person. It is not safe to assume a person is disease free. If you are not using a condom you are at risk of getting whatever STD that person may have. Many STDs cannot be cured. They can stay with you throughout your life, and put any future sexual partner you have at risk. Having sex without a condom also makes you more likely to get pregnant.

Unless the person you are having sex with has never before been intimate with another partner, you are not exposing yourself to just one person when you have sex without using a condom. When you get together with a partner, you are actually hooking up with all of that person's former partners, and everyone those partners have been with, and so on and so on. Think of it as a pyramid.

This is the number one reason that you can catch a sexually transmitted disease (STD) from having unprotected sex just once. Once might mean once, but usually means five, 10, 50 or 100 exposures.
When you are sexually intimate with one person, you are exposed to everyone they have hooked up with in their past, and those partners' former partners, and so on.
