If you have the presence of mind to keep your finger out of the triggerguard while running around with a loaded handgun and can hit a paper plate at 10 yards fairly quickly, you are ready to start. Unless you're an ex-SWAT team member with lots of experience, it will be a worthwhile eye-opener. Yes, it's artificial stress and paper targets don't shoot back, but you'd be surprised what some who preach this do when they finally put their money where their mouth is. Many never show their face again.
When I started out, I used a Glock 23 and a leather thumb-break holster. I had lots of experience with handguns and came in 5th out of 17 at my first local match. I had varying results afterward. Literally one bullet being two inches low at the 2007 MS State Championship kept me from making Master 10 months after I started. Nine months later, I finally made Master. You can be somewhat competitive fairly quickly. To get in the top 10% at a big sanctioned match takes some time. A lot of it depends on the folks you're shooting against and the quality of the stages you're shooting.
Give it a shot. Concentrate on being safe and accurate, forget speed, and see what happens. You may be hooked, or you may know to sleep in next time.
BTW, babes are few and far between, but they are there.
