是吗，这个真是乖孩子不懂了。

为毛套套会不完全管用呢？

看具体什么病了，see
http://www.cdc.gov/condomeffectiveness/latex.htm

Latex condoms, when used consistently and correctly, are highly effective in preventing the sexual transmission of HIV, the virus that causes AIDS. In addition, consistent and correct use of latex condoms reduces the risk of other sexually transmitted diseases (STDs), including diseases transmitted by genital secretions, and to a lesser degree, genital ulcer diseases. Condom use may reduce the risk for genital human papillomavirus (HPV) infection and HPV-associated diseases, e.g., genital warts and cervical cancer.

是怕被爆菊？还是自己想乱？

。。。真是年轻人的时代了。。。。。。。。。。
