I genuinely don't think there's a man alive that would realistically survive the mental onslaught of Uma girls constantly coming onto him, romantically or sexually. I'm a teacher and it's bad enough with regular teenagers constantly flirting with you, even when you know it's fake and these skanks simply want better grades. With Umas though? That shit is genuine, they either passionately love you and/or want to demolish your pelvis and have your kids. It's incredible they allow male trainers at all, the conflict of interest would be insane, especially when a notable amount of Umas do end up marrying their trainers.
