Fantasies
If mutual trust and absolute acceptance reign in your relationship, one of the most recommended erotic experiences you can enjoy with your partner is sharing your sexual fantasies. It will always be interesting to know what situations the other person fantasizes about, as it will serve as a source of spicy ideas for the future while allowing you to strengthen the bonds of trust that unite you.
When you're told a fantasy, it's important to remember that fantasies are fabrications, thoughts from a dream world that we all have inside. Our subconscious manages to adapt mental images, memories, and exciting thoughts in search of pleasurable sensations, without implying a need or desire for that situation to materialize.
It's not advisable to put this idea into practice if you or your partner might feel threatened and vulnerable by the other person's fantasies. In this sense, it's very counterproductive to confuse reality with fantasy and hear, for example, that your partner had an erotic dream with someone in your circle.
These types of couple confidences aim to break down taboos and inhibitions between both partners and never be a cause for concern or argument. The trust the other person places in you by sharing a fantasy should be rewarded and valued, so a confession of this nature should never be used against the one who confessed it, for example, as an argument during a fight.
There are also many erotic books where you can find the fantasies expressed by the author through their protagonists. If shyness gets the best of you at first, perhaps reading one of these books together will be useful, as it will help create an atmosphere while you have a fun and spicy time together.
