They are definitely not some of the cleanest individuals, but they are cleaner than needle users and hookers/clients who have unprotected sex.
1-2 times a month is meaningless. If a pornstar is hooking she is seeing multiple clients throughout the month, probably on the same day. That's how they make money. If a hooker had raw sex between her tests, then you are at serious risk.
No. It's very uncommon for a pornstar to go raw while escorting, even if the client presents some kind of 'test.' A pornstar isn't going to risk her entire career or reputation in the porn industry to go raw for a client as an escort for $2,000. She would get blacklisted.
You're spreading some dangerously false information here that could harm other people if they were naive enough to believe it. You will also harm yourself by doing this. I don't want to hijack the thread with this topic, but smarten up.
