While you are out running errands together or after a date, ask him to stop by the adult toy store. You can tell him you want to buy some lingerie to wear for him when you get home. While you are there, draw his attention to the toys. Walk around, look at them and see what his reaction is. Start out by buying something simple like pleasure gels, edible body paints, or some handcuffs. Every month go back to the store and try to graduate to a new toy that is a little more erotic. Going to the store with your man will spark conversation and it will give you a feel for what he is open to. Do not be scared to tell him what you would like to try… all he can do is say NO. You might find your man going to the store by himself and surprising you with new toys before long.
If your man is not open to pleasing you, you may want to take a step back and check your relationship. I strongly believe that if your man really likes you, he will be open to discussing your intimacy issues and be willing to make the needed changes ensure your satisfaction. However, remember it is a two way street, you need to be open to him saying he needs changes from you as well.
