Yeah, I have a similar problem; I have [firstname][lastname] as a Gmail, and I do get a good chunk of emails targeted to people who are not me.

Fortunately my last name isn't terribly popular in the English-speaking world, and my first name (Thomas) isn't super popular in Germany, so it's not a huge deal. Still, it was annoying enough to where I eventually just bought [lastname].app and set up an email for that.
