Absolutely fair advice from Azaalardons, but it isn't clear whether Julie is seeking cybers or rl matches, and I suspect the former.
If it
is for rl meet-ups, - of which I've only managed two successfully via this site over the years - my standard approach is: chat online, then talk (rules and setting), zoom (a must), then if everything still seems good, arrange meet in public place first, like a train station (I've used Cardiff Central main coffee shop), before going to location for the fight. Anything peculiar at any stage, any refusal to zoom ('Oh, I don't have a camera on my laptop' or 'my mobi can't video at the mo it's run out of storage' bullshit) just leave it to cyber or ignore. Trust your instincts.
Generally speaking tho, gyms and self-defence classes, and (I'm in Wales, remember) rugby training sessions, are great places to drop into convos 'what other sports do you like? I like tennis, skiiing and wrestling' - it's the easiest thing in the world to spot those whose eyes betray their instant interest in combat!

ps even if you follow steps above, expect 'no shows' then you won't be disappointed if they don't (again, you'll hear a lovely range of excuses - the common one I've had, three times now, 'So sorry, I had to go hospital because..' blah blah...block.
Good luck , finding an opponent online is very difficult...between the fakes the poseurs ...people who wants something different...people who have bad vibes...refuse std test....
You ll have more luck to find IRL, go to the wrestling judo or mma club in your town...train there , you ll eventually meet a women who share your kink or curious about it...
Also on internet a lot of older women and a lot out of shape women and very few minorities..contrary to the gym or the club .
