WoMon:Ahegao Response

Extreme sexual stimulation causes the Ahegao Response in PokeWoMon. Feral PokeWoMon are especially susceptible and switch to what is known as the supplication or domination reaction. If the PokeWoMon perceives itself as stronger, it will attempt to dominate the taming initiator. If it perceives itself as weaker, it will submit. Sometimes, when PokeWoMae are more evenly matched, they will fight for the dominate position in a 'Fuck-Fight' until one gives into the other. Some battles have no clear winner, and they may resume dominance displays afterwards

According to current models, this is a survival technique to avoid damaging conflicts. Domestic pokegirls are capable of consciously resisting the impulse, and the behavior is more prevalently displayed in ferals.

Pokegirls have control over how much energy or effort they put into attacks, including elemental ones. It is not all or nothing. They can instinctively deal "nonlethal" attacks because they have an intuitive understanding of what would hurt them or other pokegirls. Feral PokeWoMon are exceptionally good at selecting just the right strength of attack to use to subdue their opponent, it is believed to be the case because most Tamers train their PokeWoMon for the brute strength of their Attacks.

because of this^, you might stumble across a pack of Doggirls who are under the rule of a wild Chimera or that Bunnygirl you just battled has a Dragoness for a girlfriend

THen I was rolling with it and thinking about how the sexual competitions for dominance would work in a realistically inspired way.

During Ahegao Response with a human, PokeWoMon form a minor psychic bond that cements that human as the 'master' of their relationship.  No matter how powerful the PokeWoMon, they would all submit to their master upon forming a bond with them.
