I had sex with my younger brother but now he's ignoring me

Throwaway because this is an embarrassing topic I'm not willing to share with anyone I know.<br><br>My (20F) brother (17M) and I have always felt a certain level of attraction to each other. We've never been close but on new years eve about 5 days ago we were hanging out for a bit and I asked if he wanted to be my new years kiss. He agreed and we had a nice little kiss. Then I asked if I could give him a blowjob and he was pretty surprised so I asked if he wanted it and he said yes. It went well and then I went to sleep and that was it. The next day he texted me saying he wanted to talk and he wanted me to meet him in the living room. I came downstairs and he asked if I wanted to have sex and obviously I agreed. We had sex which was nice. Then he said he was going to the bathroom and I said "k good". So i went back to sleep and he went back to sleep. But since then he hasn't spoken to me and I'm wondering if he's okay with what happened. I'm feeling really good about it and I'd like to have sex with him again. But he's not even speaking to me so I'm not sure what to do. He's ignoring me and I don't know if he's okay with what we did. I need a way to get him to talk to me. I'm not sure if he's okay with what happened or not. I'd like to have a way to have a conversation with him in a way that makes him feel comfortable enough to open up. I'm not sure how I should do this. Any advice would be appreciated. TIA
