just need some help

my boyfriends mom went through his phone for now reason (she crazy and abusive) and saw some pictures i sent to him of me in a bra showing lots of cleavage. He just turned 17 and in 16 and we started having sex a couple months ago (100% consensual and we both were ready and wanted to do it, also we always use protection) and i always feel so shameful for doing it and mad at myself.

i’m not religious or anything but i feel so ashamed of myself for liking sex and having it and wanting to do it because i’m a girl and still relatively young.

and i feel ashamed that his mom saw those pictures and i feel “dirty” in a bad way.

I have no one to talk to cuz my bf got his phone taken and is on a trip.

Please just send some words of advice or if anyone else feels like this.
