first email creation, need email address for verification >.>

I'm making my very first email address and it asks me to input another email address or else they'll lock my account. I've inputed a fake one just so i can access this topic and maybe find a way to bypass that as i dont want to create another email address (just want one to share stuff with friends and job and 1 account is more than enough) and i don't have a cellphone (nor do i want to put my personnel phone number on the internet for obvious reasons).

So should i just create a gmail account and delete this one? I kinda need help with this before i start giving out my address to people...
