As Veronica advises, go get professional advice rather than put much reliance to what you read on the internet, including on PERB.
If you want serious advice from the internet, let me be the first to help.
Be aware that it's possible to get all kinds of things from this "hobby" even if you don't DATY. I'm really worried about these as well so I've developed a method that gives me the level of protection that I think I need to participate in this hobby.
Here's what I do.
Before visting an SP I go to Home Depot and buy the large clear garden bags (the ones used for disposing of garden waste) and a couple rolls of duct tape.
When I get to the SPs place, I tell her I have a fetish for plastic. I quickly shower and then get ready for the love fest. I hop into one of the large garden bags in the nude, with duct tape in hand. I pull a second bag over my head and use the duct tape to tape the two bags together from the inside. Then I use my little finger to punch a couple airholes in the top for fresh air and a very small hole at crotch level. I then slip an extra-large condom onto my micro-dick and push it out the hole I punched at crotch level. Using the duct tape, I then secure the base of the condom to the inside of the bag.
Now that I've taken appropriate steps to ensure the health and safety of both participants I'm ready for good luvvin'.
Much easier than messing around with Saran Wrap. Heck, you can even smear peanut butter inside your bag at mouth level and then really and truly DATY. But before using peanut butter you have to let the SP know that it's really peanut butter you're playing with in the bag.
I once made the mistake of buying the orange Glad garden bags instead of the clear ones. Spent half an hour making love to the couch before I realized the SP had left to go shopping.
Say Veronica baby, got a plastic fetish?
