Depends entirely on the girlfriend. Some things you might be missing out on:

• Soft smells from her hair, her skin, her extra set of clothes that she leaves in your closet
• Hugs, peekaboo-guess-who, kisses on the back of your neck when you're hard at work and forgot about the world around you for too long
• Good cooking, or maybe good-morning coffee, or good takeout
• Inspiration, shared jokes, mind-bending middle-of-the-night discussions
• A buddy who'll hand you a tissue during the sad parts of your favorite movies... you know when Bruce Willis died in that one, you got all choked up, didn't ya
• An enthusiastic fan of your career, your writing, your sense of humor, your (terrible) saxophone playing, your pickup games of basketball on Saturday mornings
• A convert to your football team... at least on the weeks when her fav team isn't playing yours
• New music you didn't know about
• Someone to tell about that new song you just heard... even if it's kinda cheesy she'll probably give it a try
• Stories of her life before you
• Someone to brag to, who loves listening to you brag
• Whispered sweet nothings
• A helper when you need a hand
• Someone to help—who shows her appreciation in wild and wonderful ways, like cake when it's not your birthday
• Tons of new experiences, new places to go, new foods to try, new friends to learn about, new authors and artists to consider, new lingerie to appreciate
• Someone to grow into and grow comfortable with
• Someone to tell secrets to... good ones and bad ones... without judgement
• Tickling
• Teasing
• Phone calls when your boss isn't within earshot
• Texts when ur boss isn't looking
• A hand to hold, and arms to hold you, when times are tough and you're not sure you can support your own weight any more
• A perspective very different from your own, but meltingly familiar
• Butterflies in your stomach
• The gentle jealousy of being in a secure relationship with someone who's a "catch" in your eyes—yet your eyes are the only ones that count to her
• Massages
• Caressing
• French kisses
• Spooning

• Someone to be insanely, animalistically, proud of at all times
• Someone to be insanely, animalistically, protective of at all times
• Someone to be insane and animalistic with. At any time.  ;)
