I think we all are aware of the risks associated with this but who in your opinion would be a lady that you trust to provide such a service ?

At the end of the day , the ladies aren't going to tell you if they have possible issues like open cuts and so forth so I just curious about the men that opt for such services .

It relatively easy to spot oral infectious diseases like herpes as it causes noticeable blisters in the contagious phase. Also a healthy looking tongue (free of the white build-up of oral thrush) is a good indicator of health. It is generally not possible to catch or transmit hiv through saliva as even in highly infected individuals the salivary concentration if the virus is very very low. Therefore so long as the lights are on and you can examine your partner's member/mouth for obvious sores the risk of contracting any infection is very low and for hiv, effectively zero.

Can't believe how uninformed most are. Herpes, for example is transmitted without a visible "rash" or blisters, as is Ghonoreah and Chlamydia.
Do your homework and don't take unecessary risks.
If you have bleeding gums or sores in your mouth it is possible to contract HIV from an infected WG
