ok so ur probably 17.... use half age +7...
17/2 = 8.5
8.5+7 = 15.5
15 is the lowest age for you. this goes with most people's belief that in high school, 2 years difference is the max, and 3 years difference is weird.
there was a senior a couple years ago who was dating girls like 3 or 4 years younger than him, and everyone made fun of him every day, and everyone still does. ie when he walks into a room people yell AMBER ALERT.
