I don't trust any girls

How much can you trust anyone?

Do you trust your wife?

Do you trust the other drivers on the road to follow traffic safety guidelines and laws?

Do you trust your kid’s teachers to do their jobs correctly and not cut any corners or make any mistakes that will negatively impact your child’s education or life?

Do you trust your neighbors to not run meth labs in their homes?

The net is, in my opinion anyway, that each and every one us has to make decisions based on trust that will potentially impact our lives - or deaths - every day. And, since there is never a sure thing, we assess whether whatever risk exists and decide if we can accept that risk given whatever we expect to get out of it.

All any of us can say here is that there are thousands of married guys who clearly have assessed the risk of seeing GFE girls while being married and, at least potentially, still have sex with their wives. And they’ve decided they can live with that risk.

Or have I misunderstood your question?

There are a few of the GFE providers I honestly do think are CFS always. Not many and I cannot be 100% sure on that -- some will have a BF on the side and may very well not cover for him.

 
But the real question I think you're asking in not how much any of us trust the girl is only safe sex but really what are the chances you might get infected with something and take it home. That's a harder question to answer as for some that might be 1% is too much while others might say 10% is fine and yet others might say anything more than 0% is too much. You have to figure out where you stand on that.  

 
Once you do start thinking about the probabilities of some infection if you're covered. For guys the general medical consensus is they are much less likely to get infected by their partner. (I've seen the claims but you should do some searching on the many valid medical sites that are available for search -- or use google scholar to get even better results) It makes a lot of sense. The tissue that covers our dicks is just like that covering our arms and legs and everywhere else on the outside of our body. That tissue has evolved to protect us from such external threats like bacteria. Moreover, the very outside layer is largely made up of dead cells the fall off and are replaced by other dead cells. They generally don't get infected.

 
Bacteria it self, as it moves from one environment to another, has to acclimate to a new environment. That takes about 4 hours and then the bacteria wills start multiplying -- which is when you're going to be most at risk of actually getting a disease. Just like with everything else (COVID) the simple act of washing well with soap works wonders for killing the infection and preventing disease. So take that post session shower and pay good attention (or tell the girl if she isn't) to junior and the boys. If you're doing sessions longer than 4 hours, just take a quick clean up shower (and I'd say invite the girl to do the same) shortly after you finish having sex.

 
Also, taking care to be sure you don't have some nick or scrape in your groin area where you could allow the infection under your epidermis where it can find a good growth environment (warm and moist) will help a lot.  

 
Does all that get you to 0% risk. No but I think it gets you well under that 10% level (maybe under the 1%) if you just use some common sense and are spending time with a provider that is likewise practicing good hygiene.

Tell your booker that you prefer gfe only girls so they are encouraged to remain gfe instead of getting pressured to do pse.  I know I have.

It is insane how things have changed in the past few years.  Even in third world countries, uneducated folks have enough common sense to cover up but here in the US, dumbasses are going bb with working girls.

who told us we are the ONLY guy they have done BB with?  Lol   There are only two that I trust 100%, based on my own experience, and here's why . . . .

 
They are both girls that I had an outside OTC relationship with. When I started with them at the incall, it was CFS only.  The second or third time we had sex at their residences on the outside, they both told me I was their boyfriend now, so I didn't have to use a condom.  In both cases, when I went to see them at their incall after that, they both told me when they are at work, I had to use a condom just like everyone else.  I asked why, and they both said it's disrespectful to their other customers.  I told them I would respect their rules, and I did.  We only did bareback on the outside, so I completely trusted them.  Of course, I rarely saw them at work after that.  Lol

 
With that said, there are many GFE girls that I trust enough to accept the lower level of risk.  Most of the risk in GFE is engaging in P2P slides, but I generally do that in the shower as my reviews state, using soap as the lubrication, and where potential problems go down the drain.
