Trichomoniasis is another type of vaginal infection. It is caused by a single-celled parasite that is usually spread through sex. In addition to causing bleeding after sex, it can also cause vaginal discharge and itching.
Your shower should be invigorating, not itchy. A shower may leave your skin clean, but if your skin itches after you shower, you probably find them more enervating than refreshing. How you ease this irritating itch depends on what causes it. If you're prone to allergies, your itchy skin might result from your soap, your perspiration or even the water itself.
