I'd pair up Jolteon with Vaporeon. Jolteon has spikes all over its body, and its eyes make it look very aggressive. Due to these reasons, Jolteon would definitely have to be the male of the couple. Vaporeon would be female, because of its beauty and feminine-looking body. I would also put Umbreon and Espeon together, just like Ash493. Umbreon is going to be male, and Espeon would be female.

Pfft, seen Meowstic? Females can be aggressive and males can be delicate too. But we all have our own opinions.
I guess I might be boring, but Umbreon and Espeon as well as Leafeon and Glaceon :p Glaceon and Umbreon would be females, imo. Leafeon is just cute to think of as a tufty li'l guy, and Umbreon is a dark, devious lady kinda.
Male Flareon and Female Jolteon :P I think it's interesting to have that combination of personality and gender <3
That sounds so cool, actually. Brb, writing fanfic about it. Hahah, maybe not. But yeah, most people probably expect Jolteon to be male more often, and Flareon female since it's so beautiful. I can totally see the opposite being a really colorful relationship.
A male Umbreon + a female Espeon, while cliche (and popular in this thread, too), I'd still have to choose it. Just a perfect pair.
I was also thinking a male Vaporeon + a female Flareon. Would be kinda cool, considering the colour contrasts, different genders, size differences... Just general opposites of each other. I think of it as Vaporeon protecting Flareon. :]
