杨医生: 前不久,我去北方出差,一个人奈不住寂寞,经不起一位妙龄少妇的诱惑,便与之发生了性关系。回家后不久,我发现自己下阴皮毛部皮肤搔痒难忍,常常因搔抓而使皮肤破损伴有少量出血,出血处就成青斑,我真是悔恨万分。请问,我该如何进行治疗呢? Dr. Yang: Not long ago, I went to the north for business trips. A man could not stand loneliness and could not stand the temptation of a young woman with a young age and had a sexual relationship with him. Shortly after I came home, I found itchy on the skin of the under-yin-haired hair, which often caused skin damage with a small amount of bleeding due to scratching. The bleed spot became a bruise. I really regretted it. Excuse me, how should I treat?
