Quick Tips

小贴士

If your genitals are healthy, simple hygiene is enough. Water is usually sufficient. Avoid harsh antibacterial products unless prescribed.

如果私处健康，用清水清洗即可。除非医生建议，不要使用刺激性强的杀菌产品

Men with foreskins should gently retract and wash underneath regularly.

男性如有包皮，应定期翻开清洗

Women should gently clean the vulva externally. The vagina cleans itself and does not need internal washing.

女性应清洁外阴部位，阴道本身具有自洁功能，不需要内部冲洗

Do not delay seeing a doctor due to embarrassment. STIs are medical conditions, not moral judgements.

不要因为害羞而拖延就医。性传播感染是医疗问题，不是道德问题

Many infections can occur without obvious symptoms, especially in men.

许多感染，尤其在男性身上，可能没有明显症状
