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.
Can men get yeast infections? Although uncommon, men can get a yeast infection by having unprotected sex with a woman with candidal vaginitis. It usually appears as small white spots, redness, or a dry, peeling rash on the penis accompanied by itching, irritation, or burning. Men who have not been circumcised are at an increased risk.
