Asking SO for sex

Rachel

I'm a very shy person so i am not even sure if i'm doing this right or not. I have been trying to give my SO signs that i want us to have sex by laying naked next to him, playing with his ears and just trying to get his attention subtly with my naked presence next to him. But he has just been using his phone and not paying attention to me. It's raining and i'm so horny that his behaviour is getting me really angry right now. Should i calm down and tell him in clear words "i want sex" or i should just let him be cause my body language are enough to let him know what i want
