Are gender and category right?
I don't know if you have ever gone swimming in the Mediterranean sea early in the morning, but the water is normally quiet, the rocks are empty and the sun and the breeze are soft and sweet. People take advantage of the solitude and normally swim deep, especially the young ones. They swim for long times, as you can see the bottom of the sea; the rocks and sand underneath, seaweed, fishes, occasional glimpses of one's naked body, feeling the water all around one.
After the swim some people dry up with a towel and leave. Others rest their naked bodies on the rocks softened with sand and wet plants. They get dry, with occasional waves licking their feet or their genitals, if they are adventurous. Some get aroused.
In one case the continual but irregular contact of the waves with the balls make an erection appear. The salty drops on the mouth, or drying on the nipples, the sun, and the right hand touching the cock, slowly. Looking around to see if there is anyone, and if not continuing to masturbate. The sea caressing the balls, and the increasing speed of the hand around the salty cock, fingers on the nipples and the mouth, then running down the left thigh, arching the body, caressing and making pressure on the balls, slowing down the hand that has the cock to make the pleasure and sensations last, feeling the sun, looking around to see if anyone has appeared, firmly increase speed and finally coming all over the by now dried body. In the chest, salt and semen. In some cases a drop reaches one's chin or face.
Jump into the water again, go deep into it, swim around, remove the semen from the chest and finally, get dry and rest calmly on the rocks until the tan body dries again.
But who am I and from where was I observing this?
