點解女朋友會怕羞???

You got it man.
This is the sweetest moment of a relationship. But I think you think too much. Because If you scared her, she wouldn't smile at all, right?
And like what you said your girlfriend 主動話 like you and 主動話一齊.
That is an action of bravery and you should be happy about it and cherish that. Because not every girl can do that.
I dont mind to give you my own experience, but you have to understand other people's 經驗 has nothing to do with you and it might effect on your when you make decision.

Because its YOUR relationship, use your own affort to find out the loveable, cherishable, and memorable moments for yourself. Then you will find out the 樂趣 of having a relationship.

Good Luck man

如果係我我都會啦
其實女仔同自己鐘意ge男仔表白
已經有好大勇氣
而且仲成功左
所以佢同你一起ge時候
就開始覺得唔好意思咁

所以你要主動d
男仔唔應該咁怕羞嫁

佢本身算唔算係內向既女仔呀?
可能當時佢同你表白0個陣,,鼓起好大勇氣先做到呢??
初初1齊可能點都有D怕醜既,,
不過相處多D,,了解多D之後應該會好D,,
佢對住你怕醜,,應該唔係因為你嚇親佢,,
而係因為佢鐘意你,,所以對住你比較怕醜..
佢唔敢正視你都因為鐘意你而唔敢望姐..
遲D應該會好D既,,呢件都唔係壞既事丫=]

我岩岩用我男朋友一齊都係咁....
但係一齊耐左之後,,
同佢熟左之後~
就無野嫁喇~!!!唔洗咁擔心^^
