While its good to play safe, I think TS is a bit misguided.

I don't think spraying anything or using Listerine on your dick or the WL's mouth helps in avoiding STDs. In fact, it might do more harm than good, as it could potentially upset the mouth's natural defences.

Fucking the same WL also does not make a difference statistically. The risk that each WL carries depends on the number of guys she fucks. If each WL fucks roughly the same number of guys, and assuming they use condoms, then the risk for each WL is the same, regardless if its the same WL or a different WL. Put it another way : when you flip a coin, the chances of getting head or tail is the same whether you use the same coin, or a different coin.

So there is no advantage to sticking to the same WL, unless she only sees you exclusively, or has a very small clientele.

However, it is safer to visit only legal WLs, compared to FLs. But no one knows exactly how much safer.
