Morning HARD-ON

Good Day Doctor,
I am 28 years Old and a Nigerian Citizen.
When I was a little bit younger i used to have hard -on like (3-4 times in a
week) when i woke up in the morning, not a regular hard-on, but now i rarely
have 1 hard-on in two weeks, though I am not used to having sex but when I have
the chance to have sex, i do go about 3-5 rounds maximum and my erection will go
flaccid quickly and after some like 1 day i will be back to my very strong
erection.

I asked my friends about the regular Hard-On in the morning and there response
was that "I am Having a Problem, that I am IMPOTENT".

Doctor Please Is this true...AM I NORMAL?, and what can Cause me not having
regular Hard-on in the morning.

(2) Whenever i have erection, there is always a slippery white fluid(not
    sperm, just the waterlike colour) that comes out when the erection is  
    going or goes flaccid, is the normal?

Thank you for your prompt response
