AITA for not telling my dad who got into my bag.

&#x200B;<br><br>I am 18 and was a virgin until a few days ago. My 19 year old boyfriend and I had sex in my apartment.<br><br>I have a 16 year old brother and a 22 year old sister. My father insists on us all hanging out as a family a few times a week. So we all sat in the living room. My father asked if I knew whose condoms were on the ground. I said I didn't know. My father and brother then made jokes about how it could've been the father's. They were just making up a funny story. My brother even joked about how he found them in my room. I still just said I didn't know.<br><br>My dad asked my sister. She also said she didn't know.<br><br>My dad made it clear he didn't like the idea of his children having sex, but we're all adults so there's nothing he can do. He joked about how he doesn't want to know and it's better for everyone if we keep it that way.<br><br>Later he told me I should have told him it was me. He said he'd rather know than not know. I said I'm not going to lie, but I'm also not going to tell him.<br><br>He asked if I'd do it again. I said yes. He reiterated how he'd rather know. I said fine. But only if I know he's also going to be upfront about his sex life. He said he's not and he doesn't want to know about mine.<br><br>AITA?
