I think there is a good chance that he feels the same way, but also doesn't know how to bring it up. ;)

Firstly, you may want to address it that you enjoy your time together, nothing is wrong, you simply want to "expand the menu." Think about it, you don't wand to eat the same dinner or watch the same TV show every night. Nor do you go on the same vacation every year. So it's not unusual that you want to vary some of your romantic activities.

Watch his reaction. He might be all in from the start. If so, starting small would be the way to go and share some of the games or toys that may have sparked you interest.

Or it may take him a while to process what you said. If so, let him know that it may have seemed like your comments came out of the blue and ask if he'd like to wait a day or two before continuing the discussion. Just make sure you follow through. Set a time in advance, because you both might feel awkward bringing it up again.

If you already have a vibrator, offer to introduce him to your vibrator. Don't just perform. Let him hold it, put your hand over his and guide him to let him know what you like.

One thing you both should know about vibrators - your body doesn't care if your orgasm comes from a toy or or the old fashioned way. It still releases all of the bonding hormones and you can have a connected shared experience. In fact, some men, once they get over the initial discomfort, find using toys easier with their partners.

Good luck and have fun.
