I'd say active is the way to go if you want to do stuff. I was an SP, not by choice, but it was my own fault. My suggestion is to go in with a guaranteed job. Don't let the recruiter tel yout hat you'll get the job you want if you go in Open General, or whatever. Get it in writing that you have a guaranteed AFSC.
Also, like someone else has already said, women come and go. Don't let a current girlfriend decide what you are going to do with your life. You might feel like you're too far behind the ball because you didn't go in directly after high school, but that couldn't be further from the truth. People who go in a few years later are lightyears further along in maturity, and that equates to better grades in Tech-School, which is very important. Having an Honor Grad decoration is a pretty big deal when you look back. Shoot for it.
Yes, there is a higher ratio of girls:guys in the AF, but they're not all good looking. I was one of the lucky ones. I met my current girlfriend in Germany. We lived across the hall from each other in the barracks. It worked out real nice
. She's definitely one of the very few truly hot ones to be in the military. We've been together for 8+ years now... I guess I should put a ring on her finger.
What kind of job are you looking for? Something cool? Something technical? Something Secret Squirrel?
