Anal?

So I met this guy and we really like each other and we hook up whenever I'm over at his house. We where making out and he liked to finger me while putting a finger in my butt. Which I'm fine with and then we did anal instead of regular sex because we didn't have condoms. But while I was giving him a blow job he liked it when I put a finger up his butt. Not all the way just a little. Is that weird?
