my husband's birthday is coming, what can i give him as gift?

Give him someone better to be married to.

Non monetary gift give him sex can never go wrong with this maybe throw in anal. If you got the cash maybe a new toy for instance, quad, side by side, motorcycle, dirt bike, mountain bike, kayak, boat, new truck, car, etc. Electronics and gift cards also work well.

BIRTHDAY S#X

Golf clubs, golf shoes, golf bag, golf balls, golf clothing, range finder, perhaps a membership if you feel like splurging

Your self nude

Oral, anal or anything else he usually doesn't get in the bedroom.

He'll appreciate and cherish that more than anything you can buy.

Get him tickets to his favorite band, musical, football game, etc.

Nice gold necklace.

A candy apple ruby red RoadGlide with a 1/4 fairing , drag bars and risers and a Thunder Header .

if he wears a wrist watch then give him one or a perfume or if he is into games get him an xbox :)
well you should have mentioned what he is into more.

TRUE LOVE.

Some that he can remember for the rest of his life. What that is I do not have a clue. Or get him something that he can't use and you can.

A Camaro

leather jacket

make a scrap book of your dates and life together so far and write in it too about funny nick names, feelings ect and so on

A watch would be perfect cause he will wear it daily.. :)

Xbox one , new PC, Bose or sennheiser earbuds, some clothing maybe like a tie, maybe a custom gift of some sort like a plate with a custom photo printed on it.

Give him a watch, wallet, or perfumes.

Something he doesn't have or doesn't get. When giving oral do you swallow. If you don't do it for his birthday you'll be amazed how happy he'll be. Jay has a good idea too. 3ways are fun. Don't do it with someone you know it usually backfires. I know it happened to me. My best friend and my wife started doing it without me.
