Sapphic as a Service

I mean, lesbian prostitutes have existed... I think.

So an escort and/or sex worker? They have existed at least as long as bartering has existed. LOL.

am big cis dude, hire me to send me to creeps wh try to hire one

Nah. I'd bet much longer than that. You don't have to have interactions with other traveling tribes, to have quasi religious quasi eusocial Community Support from specific members of the group. (Our Slutty Ancestors 😊)

Bartering and exchange rather than gifts, probably comes later, when your tribe interacts regularly, with people you're likely to never meet again, instead of "your village/family"

Do we have anthropologists knowing when the transition to nomadic life happened, for our ancestors (not sure we even were Homo at that stage yet)?

That's different, IMHO. That's slavery/human trafficking. And bartering likely started before nomadism. As soon as a community has enough members that not every familial unit has to have a food gatherer/hunter, you have to barter.
