如何锻炼龟头敏感的?

【咨詢人性别】男
【咨詢人年齡】26
【咨詢人病因,症狀】:本人平时喜欢看AV打枪,自从高中就开始了,不知道是什么原因,自从真正和女友做爱后,发现每次的持续时间都不一样,既试过三四分钟就射了,也有试过上半个小时都没射,最后女友都累得不让我插了,害我对着她打枪,不过自己打枪又很快就能射了……请问怎样才能保持一个长短适中,令双方都满意的时间啊?还有的就是我包皮有点长,平常状态包着龟头的,勃起能够正常露出龟头,小时候去看过医生说不用割包皮,现在我究竟还要不要去割呢?这会不会对我的性爱时间有影响呢?这么大一个人我不想去给医生看JJ啊……而且听说割了后要很久才能够正常走路。不割的话有没什么办法可以锻炼一下龟头的敏感度啊?
