Potty training a boy 👶🏽

Candi • Happy wife to a wonderful husband and momma to our 3 beautiful children! Life is good
I know this isn't related to my pregnancy (and I wasn't sure where to post)  but to my 16 month old son. I've never had to potty train a boy before as he is my only son and I was wondering what is a good age to start?
  Is now too early? And if anyone would care to share what worked best for them. I'm not sure if I should just have him watch my husband, I've seen cute little urinals u can buy or do I buy a potty and have him sit...I have no idea! lol any feed back is appreciated 😊
