Ame is "one of the boys", even more so than Mori and I say this without any hint of shitposting
She grew up as a middle child with 2 brothers, in a relatively poor family, sharing games and hobbies with them.
And then played shooters online for a decade, TF2, CSGO, Overwatch, all populated by males in voice chat.
I'm not saying she's a slut, its actually the opposite, her past indicates she's quite inexperienced and just prefers playing games with dudes, although she learned women can be ok too when she joined hololive.
Its obvious she'd be friendly to them when she found out it tempus would be a "brotuber" branch. Anything else would be against her nature.
