Question to moms

As a mother of teenagers/young adults who lived with you did you know your kids were sexually active? If so were you okay with it? I'm genuinely curious because I'm 22 and a full time student so i live with my fanily and up until i was...20 or so my mom loved to brag about her virgin daughter everytime she had one too many drinks😂 but then i see things about parents walking in on their kids and it's like just another Wednesday 😂 and then you see things like parents genuinely feel disrepected by sex in their home. I know all families are different and i can see all sides but i was just wondering if their was a side held by the majority!
