Christina: Getting Back on Track

My exercise schedule has been slip-sliding away, HELP!

The past couple of weeks, things have been looking pretty grim for this Fit Girl. My eating habits have slipped and the gym is just a distant memory now. While my waistline isn't getting any less chubby, my excuses as to why I can't get it together are running thin. The parties are over, the cake's been eaten and there are no more celebratory cocktails to be toasted with. With the marathon of birthday celebrations mostly out of my bleach-blonde hair, it's time for me to get back on track.

Please, Fit Girl friends, help me!

How to Say No Once You've Already Said Yes

Once you have sex with your BF, can you still tell him no? Of course!

At some point, every virgin faces the big "will you, won't you?" sex question, but once you've gone all the way, does the question go away? No.

Once you've had sex with a guy, it does not mean you have to do it every time you see him -- in fact, telling him you want to wait before the second time is a good way to find out if he's really into you.

Here's how to say no when you've already said yes.

Christina: Birthday Bingeing

A not-so-great cupcake fate.

It's funny how the holidays change with age. For me, Christmas used to be a magical time filled with visits from Santa, family fun and of course hoards and hoards of goodies. It took forever to arrive and was gone in an instant. Now Christmas is an exasperating experience that sneaks up on me in a flash, hits me like a ton of bricks and empties my purse faster than you can say "ho, ho, ho." Then the onslaught of "events" feels never ending and by the completion of this whole ordeal I'm a good five pounds heavier.

Don't get me started on my birthday.
