性愛/做愛問題 ....thx...

好想答你，但係由覺得太唔明白你的動機。

按新聞和性學知識
1. 最少15-20分鐘，最理想是20-30分鍾。
2. 練習和實習(練習係自己對性衝動和性器官刺激感覺的控制，實習是雙方在前奏需要，交合動作和體位的不同配合，速度和力度的不同配合，對滿足對方的需要的探知溝通，後奏的回響傳情)
3. 這個因人而異亦按心情和氣氛，所以要2。有一天你感到令她觸電的震動時(有時她叫未必係真的-所以未必可以做準)你便找到了。

1. 20min以上
2.做得多就得la
3.有經驗

touch and kiss kiss, the foreplay has no time limit, when your two feel ready then start the intercourse lor.
how long? at least 10 to 15 minutes lar, but i will say 15 to 25 minutes is better.
you don't need to care the girl got it or not, just do you best each time, that's all.
woman body is different than from man, sometime they come very fast, sometime just never come.
