Hi honeybeelamb, have to say I agree with Fr33b1rd, talking to him is really the best thing to do (unless you know he has sneaked looks at certain toys on here!).
As im sure your aware there are as many toys to choose from as there are tastes! Creating a wishlist on here together could be a great way to learn some of each others likes/dislike. I wouldnt supprise him by chaining him to a bed and producing a buttplug for example without knowing its something he wants to try.
Having said this, if you are looking for something for him the Trcey Cox range might be a good place to start, as it has something for you, him and both of you and is as couple friendly as toys could be

Good luck and have fun deciding
