Is it safe to play with the young lady the night before yesterday without any problems?

No, sexually transmitted diseases are long-term or short-term infections. Just as the incubation period of syphilis is 9 to 90 days, patients usually start to get sick 2 to 4 weeks after being infected with syphilis. Before that, you can't find any problems without checking. Another example is AIDS, the incubation period is several years to more than ten years. So, don't think that you are safe now.

In short, we must lead an honest and clean life to be safe. No way, you must also wear condoms and take safety precautions.
