... What?

Seriously?

I don't mean like, jam it into your neck to the point it restricts blood flow, or restricts your actual trachea, restricts airflow.

I mean like, lightly touch it to your adams apple, or where that would be if you don't have one.

... Can you send me your source on this?

If what you are saying is true, then massage guns of all kinds would basically cause blood clots, and I'm pretty sure they don't.

Like yeah you can potentially restrict blood/air flow if you grip or press around the wrong/right areas with enough force... but yeah, I am incredulous at the idea of vibrators being able to cause blood clots.

Maybe if you have some conditions or disorder where you have exceptionally weak capillaries, they could cause bruising, ...

... but like, I've been using a massage gun on my neck/shoulder blade for over a year now as part of a doctor / phys therapist designed phys therapy routine for me to recover from a set of injuries, and they've never risen any concerns about this, and I've never fainted nor developed blood clots from this (get my bloodwork every couple of months).

Exactly, you detailed out exactly what I had in mind!

Though uh... I'd say maybe emphasize the idea of consent, not 'platonic'.

Some people can seperate sex and love and friendship in their approaches to relationships, but lets be real, the vast majority of people cannot, when any kind of sexual touch is involved.

I would say probably don't involve people who have uh, genealogical relationships to anyone else in the group, probably try this with a group of fully informed, explicitly, enthusiastically consenting, open minded adults.

Don't peer pressure people into this.

Find open minded, kinky "freaks" instead, lol.

Personally, I'd put this on about the same tier of group activity of strip poker or drunk/strip twister.

You'd also have to have some kind of ruleset to say like, each other person can only send a total of XX seconds of vibration per song, or something like that, maybe more complex rules if you want some 'gameplay' in that regard.

The good news though is that simple bullet/egg type wireless vibes can be pretty cheap, maybe $25 or less.

The bad news is that everyone is gonna need to be ok with potentially pissing/shitting themselves, especially if people are also drinking, and they've not used such vibrators before too often.

This would probably be easier to pull off at someone's home/apartment, unless you can find a private karaoke club thats ok with people potentially pissing/shitting themselves on stage.

this is fully platonic

I think I'm those people. Let's sing.
