Safe Sex 
You shouldn’t be afraid to take control of your sexual health and safety. Being prepared, or “ready”, and being safe are healthy and smart. Preventing getting or spreading sexually transmitted infections (STIs), such as HIV, chlamydia, gonorrhea, herpes or syphilis, helps both you and your partners stay disease-free. Plus, smart use of birth control can help you avoid an unplanned pregnancy. 

Many people with sexually transmitted infections (STIs) do not get symptoms, so it's worth getting tested especially when starting a new relationship. even if you feel fine. If you think you have an STI, the earlier you're tested, the sooner treatment can be given if it's needed.An STI can be passed from one person to another through sexual contact, including vaginal, anal and oral sex.STIs can pass between men and women, and from women to women and men to men. 

The best way to prevent pregnancy and lower your risk for getting or passing an STI is to use barrier protection correctly every time you have a sexual encounter. Male condoms are the most common form of protection. you can also use a female condom. However, More is not better—using both a male and female condom can cause one or both to break. If you or your partner is allergic to traditional latex condoms, polyurethane condoms are available.You can purchase condoms at most any pharmacy or mass-market retailer. Your doctor’s office or local GUM clinic may offer free condoms. 
*It s a good idea to use a lubricant when you have sex. Condoms can tear or rip if you or your partner is not properly lubricated. Lubricants as well as being fun, can also prevent skin tearing during sex. Open skin is an avenue for sharing STIs. Use water- or silicone-based lubricants, as oil-based lubricants can actually increase the risk of a condom tearing. Read all directions on the condom box to make sure you’re using it properly. Always buy condoms that have the CE mark or BSI kite mark on the packet. This means they've been tested to high safety standards.
