You both have to discuss boundaries and limitations with each other, but, most importantly you have to be fully on board and build trust. Then start slow,don't do the full bondage experience all at once take baby steps. Who is doing the tying??
My wife enjoyed it occasionally, and I always used soft materials such as old neckties to tie her. It is important to have a safe word if he does something that you don't like.
If you trust him, try it twice, the first time you will not know what to expect or whats going on and you will be nervous, decide after the second time if it is something you want to continue. Have a safe word, if that word is not respected he will not repect you anywhere
@EmilysSecret Perhaps a discussion with him about the experience and what you did/did not enjoy, what you do/do not agree to if there is to be a next time, re @Seniorsecurity's guidance.
