As for your toy getting in between you and your lover? That won't happen either. A sex toy will never have a heartbeat, write you a love letter, laugh, breathe hot breath through your panties, eat breakfast with you, or do your laundry. It may, however, get you off faster than your lover can, and that can be disheartening.
Fear not, because when you have an attachment to your toy, it’s not actually an issue with your body as much as it is with your brain. The human brain is designed to find the fastest way to get things done. It’s a very dominant force within us. For example, if you know it should take 25 minutes to get to work and then you get stuck in traffic for an extra 10 minutes, your brain can spin out, making you angry or anxious. The same thing can happen when you wait in line at the grocery store or when you have to wait for your computer to reboot. We all know that a few extra minutes is not that big of a deal, but this very dominant impulse toward efficiency will start to drive us insane when it happens. Your brain knows there is a faster way and will try to drive you in that direction.
This is the same force at work when it comes to sex toys. Partner play may deliver an orgasm to the average woman in 10 to 30 minutes, but with a sex toy, you orgasm in four to six minutes flat. This creates a standard that your brain may hold, but your body is not "ruined." What has actually happened is that your brain has developed a new expectation. You can change that.
