You can have multiple email address of your existing Gmail account just add "+" symbol after your user name then add anything followed by @gmail.com. Read the example below for better understanding.
My Gmail id is anil@gmail.com Suppose I have three friends annu,sudheer and naveen and every person have a gmail account .so i will add their user name with my user name by a + sign.
if they ask my email address then I tell them its anil+ annu@gmail.com, anil+ sudheer@gamil.com and anil+ naveen@gmail.com
When they send me at this address it first goes to Gmail server where it recognize it as anil@gmail.com and avoids “+” sign and anything after it. So any mail send to anil+ anything@gmail.com, come in my inbox.
So If you have Boyfriend/Girlfriend tell him/her email your email id as yourmail+ yourmate@gmail.com
Note: TO check your mail you have to login as yourmail@gmail.com that is in my case anil@gmail.com without “+” sign.
