Parents found dirty texts to & from my boyfriend, now what?

so my parents went through my phone and saw some texts that my boyfriend sent me, and then went into my sent box to see what i sent him. they took my phone away for who knows how long, and im just SO mad. i mean, i know my dads paying for my phone, but he doesnt have a right to go through my personal stuff. theyre never letting me go over his house, and i dont even know if theyll let me go anywhere with him again. and its not like ive ever even done anything ual with him before. my dad says "hes dissappointed with me, and thought i was better than that." it was just a few dirty texts! i think its wrong that he went through my phone , but he obviously thinks "its for my own good". AGHHH, what i do i do? & has anyone went through this before?
