GUYS-> Does age matter? (Polite Answers only)?

OKay, so I am currently 19 and have only dated older guys since i was 15. They seem more mature, and i can p off with seeming to be older because i am a lot more mature for my age due to life experiences. I have noticed that guys tend to like younger girls, but it seems they can "Be the Boss" and sometimes i feel as if i am a "prized pet" rather than a girlfriend. I've tried seeing guys my age, but they still act like kids and live at home with their parents and have no lives... I recently broke up with my boyfriend because he said i wasn't giving him enough. I honestly didn't give him any because he was so immature. Do you guys take an interest ion younger girls because we can take more in bed, or is it something else? (oldest i have dated is a 7 years difference in age) and i am NOT a tramp, i've only slept with 1 guy in my life, and only dated 3 guys...
