A lice-killing lotion containing 1% permethrin or a mousse containing pyrethrins and piperonyl butoxide can be used to treat pubic (crab) lice. These products are available over-the-counter without a prescription at a local drug store or pharmacy. These medications are safe and effective when used exactly according to the instructions in the package or on the label. Lindane shampoo is a prescription medication that can kill lice and lice eggs.
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.
If your vaginal area feels itchy right after intercourse, you must rinse it well to stop the itchiness. Sometimes, it might be caused due to vaginal dryness. In such cases, try out a natural lubricant to cure itching. Use of condoms or diaphragms during intercourse can make the situation worse.
