The best way to protect your body (remember HIV and Syphilis are still alive and well) is to know the status of your sexual partner. Some men lie about their HIV status. Warning signs are refusal to answer the question, ambiguity about the date of their last STD tests, ambiguity about the number of partners they've been with, and willingness to have sex without a condom among others. Protect yourself by assuming your partner is positive until proven otherwise.
