Can pre-cum touching the outer (opening) area of the vagina make you pregnant? no penetration, no full ejaculation,peed 2 times since last ejaculation

It's complicated: There are probably few if any sperm present in the Copwer's gland secretions you describe, but there is a risk of pregnancy if any amount of seminal fluid (which definitely contain sperm) are deposited in the vagina.

Almost next-to-zero: All your described scenes pose an almost next-to-zero likelihood to get pregnant, but never at 100% guaranty. Of course, we need to remember and accept the facts: No known contraceptive measures can give a 100% success; nothing is free / perfect, but always comes with a price. So, do the possible best to implement currently available contraceptive ways and be responsible to accept the consequence.
