Ummm, now I want to edit my comment since I made a statement that has no concreate backing, just off handed comments. but I will leave it unedited for discussion and to see how other people feel.
There are few comments implying that Brint leaves few bastards here and there as result of his sexual prolivities (like one conversation between his mother and the champ) which, considering that his and champions pregnancy are basicaly unplaned since he does not use protection or contraceptives, I am personaly willing to take at face value. Which for me is ew ew ew ew ew ew. Maybe it is just me, but considering that game tries to make him seem like romantic interest in lue of our lack of male suitors, that really kills my interest in him for reasons I hope I do not need to explain.
And even if it is not true, them just them being off handed comments, it is still ewwwwww from me. Like, considering game tries to present Brint as something more than a traditional macho man, for the game to go "look how cool Brint is by the metric of how many potential children he could be having" is still... yuck. I am certain that it appeals to some people, but I am traditional person in that regard.
Than again, I was never that into promiscious men unless I could turn them into loyal husbands. So some of my biases are seeping out.
Edit: You know, I wanted to bring up how all of our male companions are promiscious and how good female lovers have it, but than I realized that only two companions can be considered traditional waifus, and how both of them are the ones I do not really care about (Kiyoko and Brienne). Which is interesting. Considering how popular they seem to be with male playerbase, I would have expected more of those kind of companions.
