Ask for sex? Desperate?

Is it bad or weird to just straight out ask for your husband to have sex with you? Will I seem desperate? We haven’t had sex for 2 weeks and I’m just frustrated. Last time I tried lingerie he was playing a game and didn’t even look up. I tried on 3 different outfits and all he could do was look at me real quick, say “that’s nice” and go back to playing. Any tips?
