That's why I prefer ppl sharing there experiences either way. If you look at the published statistics for Sti data for 2014 there are approximately 8000 cases in heterosexual men (it seems to be much much higher in gay men). 8000 cases is not a lot taking into account repeat cases etc. also reading people's comments who claim they caught it from owo they always make out they experienced all symptoms, burning discharge and swollen bollock etc. so I think trolling and scaremongering are out there.
Anyway I have made my decision to stop now and peoples experience did help I guess.
I think you've had the full gamut of responses on this thread.
As Smiths and others have said, it's a risk-to-reward ratio with oral sex. In all fairness, I worked on that same basis too, and for close to forty years, between tarts and civvies, I have no idea how many uncovered BJs I had. But let's say it's 200+.
You could go your whole life, a BJ a week from someone different each time, and never catch a thing. People do.
But then if you get gonnorhea, and people do, all the time, it's a real fucker.
Therefore I'd advise against OWO but only in the same way I'd advise against smoking. In other words, I wouldn't expect anyone to stop just because I said so. You got to work it out yourself.
