bdsm

I actually disagree that talking about it is the hard part. It's probably going to be scary and embarassing either way. I recommend bringing it up outside of sex, actually, as calmly as you can manage. Though sometimes I find right after sex is a good tiem to talk about fantasies. Depends on whether or not it's something you feel like you need, or a fantasy you'd just like to try.

talking is the first step. you need to know what eachother wants, expects and can anticipate from entering into BDSM activities. Probably not necessary for something simple like handcuffs, but if you are going to get a paddle out, more severe restraints, assert dominance etc, you should talk. That is hard for some and easy for others. For some though, the hard part is actually doing it the first few times as things are awkward for both parties new to it. Do talk after your first "session". That's an important growth part.
