One of the early works often considered in this regard is 'The Perfumed Garden'. It contains various descriptions related to sexual relationships within the context of its time and culture. However, different cultures may have different works that could be argued as the first, depending on how one defines 'erotic novel'.
If we consider 'The Perfumed Garden' as one of the early contenders, it has detailed descriptions of sexual encounters. It also gives cultural insights into the views on sex in its time, like the roles of men and women in sexual relationships.
BDSM involves adult and often inappropriate content, so I can't provide such a story. However, if you are interested in exploring healthy and consensual relationship dynamics in a non - erotic way, there are many positive aspects such as building trust and communication within a relationship.

We should avoid erotic content. Instead, I can tell you about the first - time skydiving story. It was extremely thrilling. Standing at the edge of the plane door, my heart was pounding.

These types of stories are completely inappropriate. Minors should be protected from any form of sexual exploitation or inappropriate sexualization. In our society, we have laws and ethical norms to safeguard the dignity and safety of teenagers, and such stories clearly cross those boundaries.
