Boyfriend's birthday is coming up!!

Go to www.thinkgeek.com. A lot of cool stuff. You'll find something there

get him something meaningful, like the typical "chick" gift that will show him that you love and care about him.. also get a gift card from gamestop or EB with enough for a game or something and put it in a card..

he'll open the gift and like it, and then open the card and realize you thought about his interests as well..

Alright, I suggest something either steampunk-themed.

I also suggest maybe a car charger-splitter? Solar panel chargers/ solar panels in general are pretty neat. An FM transmitter for an ipod makes a pretty good gift. I suggest some sort of dice? Maybe novelty dice (gold plated)? Lambskin condoms if you're sexually active and have had bloodwork done with your partner to confirm you both don't have STDs (they feel amazing but that's their one downside, they don't protect against STDs).

I also suggest maybe getting him a retro console. You can pick up an old N64 with controllers, cords, and even a few games as a bundle for maybe $100. Don't get an old playstation- if your boyfriend has a PS2 or PS3, he can just play all his old games on that.

Maybe look around for a signed copy of gary... uh... forget the guy's name, but he's the one who invented Dungeons and Dragons. See if there's anything autographed of his on ebay. Good luck.
P.S.
I'm a bit like him from the sounds of things- the best present I *ever* got was a handmade pillow. I'm lying on it right now, and I still think of the woman who made it for me.
