Dating Merman Sinbad would include…
Sinbad would be among the most beautiful and majestic creatures to roam the seven seas. He takes pride in his appearance and grooms often, not a single scale on his body would be out of place as well as his silky locks of hair would be groomed with precision. He is truly a sight to behold, and one would be lucky to ever see him because he very particular of who he allows to view his glorious appearance.
His beauty is something that he uses to his advantage, like a siren. He has been known to use his body to seduce sailors lost at sea then bring them down with him if he deems them unworthy lovers or have ill intentions that he deems hostile and dangerous. Although this is not a daily occurrence, it happens more often than not.
He has four eyelids - the layers consisting of a regular, salt water, freshwater, and a mucus layer using each depending on the environment he is in. He uses each sparingly because he is very adventurous and finds himself in strange lagoons or bays. Originally he was born in a fresh body of water high in the mountains but later left the nest to explore the ocean
Because he has explored different bodies of water, he can easily adjust to the temperature and salt water differences easily. He prefers to stay in fresh water, but does not mind exploring the salt ocean water for ship wrecks at the bottom. It is most likely he found his djinn in a shipwreck in the deepest part of the ocean buried under lost treasure as well as other weapons and accessories.
He is a very curious amphibian and loves to broaden his horizons. Sinbad would silently observe people by the shore, completely unknowing of the creature studying their habits and behaviors. He will bring his face only just above the current to watch closely and study the different shapes and types of people. This is most likely how he would have met his S/O.
Sinbad would know more about his potential S/O before they would even discover his existence - due to him partly being shy but also observing silently to judge if you were to make a suitable partner.
Once he deems that you are indeed a worthy partner, Sinbad would be anxious for the very first time to try and make his presence be known to you. Being the stealthy creature he was, he eventually approached you on the beach once he ruled that you were no threat. It initially shocked you how someone could sneak up on you like he did, seeing as you were almost sure there was no one on the private beach.
After he tried to apologize to you through hand gestures for possibly having startled you and slightly startling himself in the process by your frantic reaction, you calmed down and said it was alright, asking about his origins in the process.
The conversation would be mainly one sided due to his voice coming out very high pitched and gurgled with water in his lungs, his voice almost like a scream but was also melodic. He would dip his head into the water and answer questions, where you can actually head what sounded like words.
Once you both established a connection to converse, Sinbad would continuously ask questions about the strange behaviors and customs of humans on the land. He has never seen a human up close before, so he is very perplexed and ready to learn any new information you are willing to share with him and he in return.
After a friendship is established, Sinbad is more generous. He often brings his S/O treasures he had found at the bottom of the ocean or certain rocks that he believed matched their eyes. He is also pretty crafty and will create necklaces out of pieces of lost jewelry for them.
This also applies when he is trying to court them. He wants to be able to provide for his mate, and thus he will only bring them the best. He will kill the largest predator he can find to bring as an offering, giving them a sharp-toothed smile on his behalf.
Although Sinbad has flirted and perhaps mated with a couple of mermaids across the ocean, he finds that he is committed to being with his human S/O and puts them on a higher pedestal than his past lovers. Thus he will begin to genuinely court them instead of giving regurgitated compliments that he has carelessly thrown to other sea women before them.
Finally, he will just straight ask them if he can court them and begin a relationship. Sinbad is not one to beat around the bush, he will bring them an assortment of seashells and treasures with seafood at the side to make the evening special before he will ask them. He is initially nervous about asking, because he is still limited with communication and settles for hand gestures, but becomes ecstatic when his S/O accepts - resulting in his tail splashing around.
He is still genuinely curious - he does not understand the rituals for courting humans and sometimes does not understand their facial expressions or odd habits. He loves when his S/O brings him food that they have made, because he has honestly never eaten a hot meal before and absolutely loves it - demanding they cook for him from now on.
Sinbad also appreciates when they bring him books. It does not matter what kind, but he loves the thought of knowledge being pressed between two covers. He tries to bring them on his journeys, but sad to find that paper and water do not mix well. However, he will settle for having his S/O read to him by the sea shore.
When the relationship is official, Sinbad immediately becomes very loving and doting of his human S/O. He cannot wait to get them into the water so they can spend time together swimming or just wading in a pool together in each others arms. If his S/O does not happen to know how to swim, Sinbad is an excellent teacher and patient - making sure to always keep his arms around their waist in case they drown or begin to sink.
Speaking of swimming, Sinbad enjoys taking his S/O on scuba dives. He will take their hand and lead them to breathtaking views under the shore that only he would know about, allowing them to interact with the various types of fish and plantation.
As time progresses, Sinbad eventually suggests he move in with them - or visit temporarily in their home. He cannot stand the thought of being parted by the land and sea, wanting nothing more than to just enjoy human things with his mate while cruising his condition that binds him to the water. His S/O would manage to eventually set up a pool in their living room or fill up their bathtub with water. Getting him to their home was a struggle, but well worth it once he was greeted with all the new human devices around him, while also being able to see his loved one everyday
Now that Sinbad is with his S/O inside their home together, there is no excuse for them to finally be able to enjoy their time alone together. He will wrap his large tail around their waist and legs while pulling them close to his chest in a strong embrace. Again, the communication is limited but his actions speak louder than words.
Overall, your relationship with merman Sinbad is a very adventurous and curious one. Because you are both different species, you’re always learning new things about each other and sharing your culture and habits with one another. Regardless if you are human or not, Sinbad really cherishes his S/O and is glad he had met them - and hopefully in the near future plans to bring his relationship to a more committed level.
