扯旗時龜頭未能露出!!!

young man, 扯旗果時會唔會龜頭外露? depends on how LONG your 包皮/foreskin is ...
if it is too long, 龜頭唔會外露 ! if it is ok long, half 龜頭 會外露 !
it is very normal for you to feel uncomfortable or painful the first time to flip all
the foreskin back during sex ... when you have more sex or use to 龜頭外露 !
龜頭 will become less sensitive and you won't feel painful anymore...
if it is really too long, you can talk to family doctor to decide if you should have the foreskin cut off, as a small surgery ...
good luck la ... you are fine... make sure you wear condom with gf ...
to protect yourself and her ... because the longer the foreskin ... the easier it trap dirt and bacteria ... you have to clean it well enough...

正常！不過除了令你做愛時感到痛楚，不能享受其樂之外，亦是非常的不清潔，平時涼時，應該將包皮反起，清潔乾淨；另外，亦很容易令女方感染，引至宮頸炎，甚至宮頸癌。可以去見醫生，做包皮手術，一石二鳥。

你都未發育完，未出頭，龜頭連着陰莖是正常的。遲啲會有出人頭地，唔駛急。

not only is your foreskin too long, also the opening is too small, best to consult a doctor to see if it's removal is needed.

in normal cases it should NOT be painful at all

是否包皮過長？

平時都會外露的。你要醫生看看。
