I wasn't looking for sex with this person. I'm always into the owo and to be honest I don't think there is any more risk from catching something from her as any other working girl that performs owo. Her reviews for that were really good, that's what I wanted from her.
She doesn't have any reviews for that or anything else, not on here at least and that's where it matters. AW feedback is unreliable garbage and when the positives are actually accurate there's almost no way of being able to tell (unless you come to trust the feedback from a specific punter because his experiences have always matched yours but even that's unreliable). The only thing you can repeatedly rely on is negative and neutral feedback, that's almost always accurate.
Anyway, other escorts won't know why you've seen barabackers or what you did with them, they will just presume the worst. If you try to "explain" they'll just presume you're lying and they'd also be very right to, because you don't need to see a barebacker to get a good blowjob.
As for your question, I've experienced almost the exact same too. It was just age I had listed on my profile. For some reason the daft bint thought I was actually being accurate with it. To change the age listed on your profile, obviously login to AW then in the drop down menu for "My Details" (next to "Search"), select "edit profile" then "profile details". It'll take you to your profile but it's automatically on the "General" tab, you need to select the "Personal Details" tab, then at top you'll see your date of birth. Change it to whatever you want (although I'd recommend not lying too much because you'll probably not get good service from someone who thinks you're too old but only finds out when you arrive). Note that escorts can't see your date of birth, to them it just shows your age.
Of course you can always just not show your age by deleting what you put in the date of birth box and clicking save. Click onto something else and then go back to your profile (specifically the personal details tab) to check your date of birth is still blank just to make sure.
