40 couple, married for 20 years. I'm much more liberal and adventurous about my sexuality and she is very reserved and conservative. I have a variety of kinks and she is very vanilla. She does indulge in my kinks from time to time more as a show of affection for me than her own enjoyment.

Lately she's showed some interest in exploring more than vanilla sex. She asked me about my kinks or things I'd like to try. It took me off guard so I was unprepared but articulated some wishes. Her asking that was a big step for her and I'd really like to encourage her to talk more about sex and explore but I don't want to be overbearing.

How can I encourage her to explore her sexuality, without being overbearing? What are some ways she could expose herself to new sexual ideas, themes, kinks given she is not in the least excited by porn and still very conservative?
