This means taking steps before and during sex that can help prevent you from getting an infection, or from giving one to your partner.</p><p>Before having sex:</p><ul><li>Get to know your partner and discuss your sexual histories.</li><li>Don't feel forced into having sex.</li><li>Don't have sexual contact with anyone but your partner. </li></ul><p>Be sure that your sexual partner does not have any sexually transmitted infection (STI). Before having sex with a new partner, each of you should get screened for STIs. Share the test results with each other.</p><p>If you have an STI such as HIV or herpes, let any sexual partner know before you have sex. Allow them to decide what to do. If you both agree to have sexual contact, use latex or polyurethane condoms.</p><p>Remember to:</p><ul><li>Use condoms for all vaginal, anal, and oral intercourse.</li><li>Make sure that the condom is in place from the beginning to the end of the sexual activity. Use it every time you have sex.</li><li>Keep in mind that STIs can be spread by contact with surrounding skin areas. A condom reduces your risk but does not fully eliminate it.</li></ul><p>Other tips include:</p><ul><li>Use lubricants. They may help reduce the chance that a condom will break.</li><li>Use only water-based lubricants. Oil-based or petroleum-type lubricants can cause latex to weaken and tear.</li><li>Polyurethane condoms are less prone to breaking than latex condoms, but they cost more.</li><li>Using condoms with nonoxynol-9 (a spermicide) may irritate vaginal or penile tissue and thus increase the chance of HIV transmission.</li><li>Stay sober. Alcohol and drugs impair your judgment. When you are not sober, you might not choose your partner as carefully. You may also forget to use condoms, or use them incorrectly.</li></ul></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Alternative Names</h2></div><div class="section-button"><button type="submit" aria-controls="section-Alt" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
