How to get alone time with my boyfriend? (teenagers only please)?

Alright, I'm 17. and i am ready to have sex. i dont care what anybody says about it. i know my body and i know what im ready for. we are taking all of the precautions possible. and this guy has been my boyfriend for 5 years. and im ready for this. i want it. im graduating highschool around june of next year. and my parents are really overprotective and they haven't even let me be alone at the house with him. this question is only for teenagers, because i think they would understand the situation im in better then any adults would. do you guys know anyways that it would be easy for me and my boyfriend to get alone together? THANKS GUYS ! =]
