I ask prior to meeting if they test and when their last test was done and insist on condoms for penetration.
I have no intention on even meeting with anyone that doesn't test on a regular basis and agree to condom use - it would be a waste of time all around. (Profile states condoms are a must)
If met up with someone and found out they didn't test and refused to use condoms that meeting wouldn't last longer than it takes to find out that information.
"It was nice meeting you but I'm not comfortable with what you are telling me, we are looking for different things so I am going to leave."
Then block them when I get home.
