Quoting awuffleablehedgie, reply 22really, competitive multiplayer means all players will play as Females for the quicker marriages.
I don't follow. Female sovs don't really have an advantage now that Janusk won't marry until after a certain prestige level. I find about 50/50 male/female heroes out there. It's really a shot in the dark.
It does make a difference because as a female, you guarantee that you have Janusk at the least will be there. If you go male, then you need to find out a female hero wandering around. If you bump into only male ones, you're screwed. OTOH, with a female sovereign, even if all the ones you find are female, you will always have Janusk.
Personally I think the best solution would be to make it so that Janusk starts as the opposite sex to what you select. If you're a male, he should become Januska

Another possible solution would be to alllow your sovereign to marry another faction's children. Perhaps some of the neutrals?
