? seems like a red flag what do you say guys?

I started talking to a guy after he initiated contact on a dating website. We get an email when there's a new message on the site. The ( ridiculously good looking) guy said it sounds like we want the same thing but he's not on the site much so could he have my email. My email? not my number. Does this seem weird?
