1. ANYONE who engages in this hobby should be regularly tested for STDs. You can get things like Herpes even with a condom. Also, you can get (and pass) STDs through oral sex. Several porn stars have told me that they got gonorrhea of the mouth from blowjobs. If you don't use a dental dam, you can get (or give) an STD from eating pussy. Yes, transmission of STDs through oral sex is considered a rarity. But, it can and does happen. The more you do it, the more risk there is.
2. Many escorts, and porn stars, DO offer bareback sex. Some with regular clients only, some with anyone who shows up and asks for it. Some ask for tests. Some don't. There are plenty of backchannels around where people pass around information about escorts who are willing to do bareback sex with anyone with or without tests. Some sites even list that information in their reviews. Note that I am not saying here that ALL escorts do it. But, there is a significant portion that do. And, according to some statisticians and surveys, bareback sex in the U.S. in on the rise in general.
3. STDs are not the only risk from unprotected sex. Not all women are on birth control.
4. IF you are going to engage in bareback sex with an escort, and are able to and willing to pay the rates that porn stars ask, what is another couple of hundred dollars to get tested? It's easy and relatively painless. If you really want to fulfill that fantasy, or reenact one of your favorite scenes, why not spend the extra money and do it right? If the woman is willing, that is.
5. I am making NO comments here about whether or not anyone should or should not engage in bareback sex. It is a PERSONAL choice. Just get tested. I know Moose gets tested. I do too. So should you even if you don't want to engage in bareback sex.
