Owo is such a difficult topic. It's like brexit, arguments on both sides.
I do provide owo with conditions to minimise risk.
Firstly, every client that walks through my door HAS to have a shower. No ifs, no buts. I dont start the clock during that time so my clients know the time starts when in the bedroom.
Obviously any lumps or bad smell would prompt me to say condom only but honestly that's rare to see because if any has a smelly dick which looks unhealthy they are not likely to go and see someone.
In my honest opinion, I do think if i stopped doing owo it would massively effect my work load. In over 2 years, I've rarely had someone specifically ask for oral with a condom.
On a side note with health, minimising risks etc. I've not had any infections in my 2 yeara of working giving owo. So whilst it's possible, taking risk reduction etc does keep chances low.
Just my opinion.
