My parents arent giving me privacy, what should i do?

kso, the other day my friend thought itd be funny to go buy condoms as a joke. they gave me two so i simply put them in my purse. I told my parents because i knew if they were to look in there they'd flip out. I even told them i wasn't planning on having sex anytime soon. So this morning my mom woke me up and told me my dad took my phone because there was bad messages to guys on there. The thing is I told my dad that me and my friends text people random stuff all the time. i told them i didn't mean anything that was said and that the people knew it was a joke. I honestly don't know what to do about them they don't give me ANY privacy.
