Yes, Twinkle was the start of my mag obsession too, followed by Bunty, then Girl (anyone remember that) I was about 10 and my Mum had to check it first - I remember being scared because there was an article about periods in it, but luckily my Mother saw the sense of such an informative article and let me have the subscription.
After that things went a bit mad, Just 17, Mizz, Smash hits, Sky, 19, Mix Mag in my teens. Cosmo, Company, Marie Claire, Elle, Vogue, Minx, Ok, Now, Heat, Nova, occasional copy of Slimming World and National Inquirer, ALL the baby mags, takes me to now. Glamour is my fave at the moment, cheap, small good articles (friend who works on it, plug, plug!)
Financial reasoning has (partially) taken hold of my life so limit them to 1 weekly (usually Now), my sub to Glamour (only a tenner, and birthday present anyway)and possibly a Marie Clarie.
I agree with Emmam looking at celebs in dodgy photos rocks my boat too! And don't worry, Cosmo seems a bit tedious to me at 26, I really think they just churn the same stuff out over and over again, once you've read one....
I happily admit to being a mag-a-holic and on occasion I will have a 'binge' and buy loads in one week. It's a mixture of guilt and euphoria as I hand over my cash, I'm coming through it now though...It's been a long journey but I'm nearly there...!
