Ever wonder why the sea is salty?

It doesn't take long for the male to ejaculate, around 40 seconds to a minute, and this is usually accompanied by either shuddering just prior to ejaculating, and thrusting and tail-arching during ejaculation. The force of ejaculation can be powerful at times, so it is best to keep your face out of the line of fire, or keep his member underwater. You can attempt to lick and suck on the end of it while masturbating as well, but be warned, do not try to give full throat, and get the hell out of the way before he ejaculates! A male dolphin could snap your neck in a accidental thrust, and that would be the end of that relationship.
Mating: This is harder. Obviously, being human, it is awkward, but not impossible to mate in open water. It is easier to have the dolphin in a shallow area (like the shallows just off the beach) around 1 1/2 to 2 feet deep. This is usually comfortable enough for both the dolphin and you.
