Risky behavior can lead to an increased risk of health and emotional issues. This increases the risk of sexually transmitted diseases, unwanted pregnancy, or being in a relationship that is damaging emotionally. High-risk sexual behaviors can include: • Unprotected intercourse • Unprotected mouth-to-genital contact • Multiple sex partners • Having a partner who has multiple partners or other risk factors • Unprotected anal sex or having sex with a partner who engages in this • Having a partner who injects drugs • Sex work   Other factors can include not understanding your own sexuality or not being able to express what your boundaries are. These can lead to engaging in sexual relations that do damage to you emotionally and possibly physically.   Health issues can be risk factors, as well. If you are dealing with a hormone imbalance or chronic disease, your sexual health can be affected.
