It’s a good thing to push the boundaries of your BDSM experience from time to time because it helps you both create a more exciting experience. By pushing past your limitations, you not only get a more intense experience, but you will also get a greater rush of adrenaline. In addition, exploring your own boundaries with someone else will enhance your trust in each other, and it willhelp you both to have a stronger relationship as a result.
You never know how far you can go until you try to go further than you’ve already been. That said, you don’t ever have to go any further than you want to if you’re not interested. That’s why you talk over the potential changes to your relationship first. If there’s no room for compromise, there’s no room for change.
If you partner refuses to budge on their limits, then you must respect this. But if these new ideas are something you have to try or you need in your life then perhaps this is a sign you need a new partner to share what you want from your BDSM play. This does not mean you leave your partner because they don’t want to try it rightaway or are unsure. Many things need to be considered when deciding to leave a serious long term Dom/sub relationship.
