5. Trichomoniasis
Trichomoniasis is the most common STD in sexually active young women. Some women may mistake this infection for a yeast infection or bacterial vaginosis since the symptoms are similar: frothy discharge, strong vaginal odor, pain on intercourse, irritation and itching. Men can get trichomoniasis too, but they don’t tend to have symptoms. If you are a young woman who has been diagnosed with the disease, make sure your partner gets treated. Trich may not be affecting him much, but you don’t want him giving it back to you! And, if your partner is a woman, you could be passing the disease to each other as well.
