Hmmm...can being on a porn site count as a reference?
"I'm in a porn" - no
"Hi there, I'm Maxx Cockz and I work for Vivid Entertainment. The direct number is XXX-XXX-XXXX and my bosses extention is XXX. My real name is John Smith and please feel free to ask him about me" - Maybe
There may be more BB in porn, but there's a ton of testing too. I also operate under the assumption my clients all BB with someone (be it a wife, girlfriend, or free bar girl on the weekend) and I don't know what the "someone" does with others. The rule is "you sleep with everyone your partner has ever slept with".
I don't know if I *personally* would see someone who does tons of condomless films, but I'd definitely see someone who wore condoms in their films. That doesn't bother me in the slightest.
