Hickey

I’m 15 years old (I’ll be 16 in two months) and I got caught with a hickey not once but twice in the last three months....My mom is super upset and has grounded me for two months....I’m pretty mad but I can kinda see where she’s coming from....I didn’t have them out and open either..I had them hidden pretty well and she only saw the ones on my neck (towards the back of course) and not my chest so I’m not sure how i should react to this...She said it was slutty and that I looked easy and said I have 0 trust now...It’s just frustrating. Any suggestions? I’ve cleaned the WHOLE house and have been making dinners and everything...it’s only two weeks into my two month grounding and i’m hating it.

EDIT: My Hickey came from a girl..my mom is a very strict christian woman...she would be very disappointed..
