Welcome to Boxer & Rice

Saiyans can have seven different types of orgasms, all of which are increased when the Saiyans are bonded (not claimed);

*Penis, duh XD Most intense orgasm, on par with 'genita' and 'chakra' orgasms.

*Genita/Breeder/Mating Entrance (Cervix), an ongoing orgasm that diminishes after every wave. Similar to a human vaginal orgasm.

*Prostate, not much to be said. Humans also experience this.

*Tail/Tail gland, (anal stimulation and exterior stimulation) particularly intense in lockers. If stimulated enough, it will produce a climax-like sensation at the base of their tails, sometimes radiating through the entire tail. Not very intense by itself, but enhances other orgasms tenfold.

*Ki/Energy/Chakra stimuli, saiyan energy can spike/mingle 'inside' their partner's energy and cause them to have body orgasms. A reason why they're very sought out as lovers/pets/sex-slaves by other species.

*Nipples, especially in latchers. When they get close to their heat, they overproduce (hormone is similar to androstenol) a milky substance throughout their body, which acts as an aphrodisiac. The climax is not as intense as others, but if left 'unattended' can drive a Saiyan crazy from arousal. So, latchers NEED to be milked, like- from everywhere.
Lockers also experience nipple orgasms but in less intensity.

*Battle lust, Saiyans experience 'brain' arousal (the part of the brain that triggers an oozaru transformation?) when in an intense battle. Pain often triggers it. It's a burning sensation at the base of the head. It often goes hand in hand with 'penile' arousal.
