Thanks for your query.Based on the facts that you have posted it appears that you have problem of Premature Ejaculation
The white sticky discharge you get even with slight excitement is nothing but a secretion of Periurethral glands located in urethra.
This is normal secretion of these glands which help in free passage of thick semen through Urethra during ejaculation. This is excessive in your case .It will settle down itself once you get used to normal sexual life
. As regards premature ejaculation this is due to anxiety
.Please consult qualified Urologist/Sexologist
for advice regarding treatment. You can take Tab Dapoxetine
to resolve this issue.
