Each to their own. I know when 50 shades came out my wife wanted to try some tame things that interested her but for me I like a little harder. I have been a fan of the Kink website for sometime and i am gently introducing things into our bedroom.
The biggest thing is comfort and taking it slowly if there is any trepidation of certain things. Depending on your partner it may be a short conversation in the bedroom at the very least. it is also good to establish boundaries early in the relationship and have open discussions about this with you partner.
