Moms out there! Help me with this situation with my own mom?

First off, i'm 16, soon to be 17, and i am in a relationship with my first boyfriend...we've been dating for 3 months and we've kissed, which apparently my mom has issues with. She asked me if i we had kissed a week after it had happened, and i told her the truth, and she flipped out on me and told me that was unacceptable and that i am not allowed to kiss him. So i told my boyfriend and he completely complied (he's a GREAT guy and would NEVER cross a boundary or harm me in any way). So it's been about 3 weeks since we agreed to not kiss, but it's getting unbearable for me! And i know it's killing him too! If you were my mom, what would you think of your daughter that was sneaking kisses (something that is blatantly disobeying your demands) behind your back? Thanks for everything!! :D
