It's a fact that if you've never used a sex toy, broaching the subject with your significant other can be downright scary. In many people's minds, sex toys are equated with giant silicone penises, and what man wants an opponent like that in the bedroom? Luckily though, there are many less intimidating options that won't scare away newbies.
First, always be as open as possible about your needs ahead of time. Communication is the key in any relationship and this translates to the bedroom as well. When you bring up the subject of a sex toy, stress that it is an enhancement to sex similar to candles or music. Make sure he knows that he pleases you and that you would like to explore a little and see where it goes together. Most likely, he'll want to please you as well and will be equally curious. Start small and choose the toy with him so you are both involved in the process. If your partner is still against using a sex toy, buy one on your own and give it a test run solo. With time, he'll probably change his mind and want to see it in action.
Another way to introduce a sex toy is by giving him a preview. For example, if you want to try bondage, try something light and playful such as holding his hands above his head during foreplay. This way, you can see how he'll react before actually whipping out the pink furry handcuffs. If all goes well, then proceed with handcuffs. Likewise if you're looking for him to stimulate you somewhere else, for example, place his fingers there and gauge his reaction before introducing a sex toy that might make him feel uncomfortable. The point here is to show him that the toy is all about your pleasure and not there to make up for his shortcomings. Once he sees that he will turn you on even more with the toy, how can he resist?
Remember that intimacy is the goal. Only you know what works in your relationship and by communicating honestly, you are building the foundation for a healthy relationship in the future. It is entirely up to you to decide whether that means with or without sex toys, but a little experimenting never hurt anyone.
