why cant i get privacy?

to preface. i am an 18 year old girl. i live with family (mom, stepdad, stepsis, brother) and i am a nymphomaniac. so obviously i masturbate.

i bought my own phone. i was doing things at 10 pm and my mom walks in without knocking (normal for her to the hatred of my whole family but mostly me as the youngest and most sexually open) she saw me scramble for a blanket and she just rolled her eyes and said "give me your phone" meaning i won't get it back for a long while. i wasn't sending nudes (at that specific moment) i had my door closed and i wasn't being loud or anything.

previously she caught me sending pics and said "just masturbate alone" and for all she knew i was. i can't get any satisfaction ever anyways so why do i even bother?( i cant orgasm)

i wanna cry

very bad idea sending sex pics to strangers. Someone could be underage and you could get into trouble. I guess you can't get privacy because your mother doesn't trust your judgment.

I think the answer to your question is simple.. "because you're a minor sending nude photos of yourself, online".

It's a safety concern. Your mom is worried, scared, and trying to prevent you (and your family) from getting hurt.

Two good pieces of advice from previous people. Also, once you send it, it's out there. Once it gets on the Internet, it's forever.
