OWO is low risk in my experience is what i posted earlier, The Donkey Work disagreed as his posts show. He even says the risks are the same between BB and OWOto all intent and purposes, the ramblings of someone who is clueless in my opinion, and who thinks i need educating about the risks, whereas its him who needs to given his posts and thinking.
Now who is getting personal?
You're a fragile personality... I can see that, so I'll not escalate matters - wouldn't want you crying on your farley's rusk.
To properly address the risk you need to accurately assess what the risk is between the two competing activities: bareback full sex and bareback oral. There are plenty of folk (Wife4Rent for one) saying that they have regularly and consistently engaged in bareback sex and not caught any nasties.
I have had plenty of casual bareback sex in the past (admittedly not with working girls but in my youth with many nightclub randoms) and I never fell victim to anything.
I have, however (and I recognise that you are having to take my word for this) been in a situation where I know categorically and beyond all reasonable doubt that I have contracted Chlamydia through receiving oral sex.
Many of you believe that because you have engaged in OWO and not caught anything it is safe and low risk.... but who is to say that, going by that yard-stick, you wouldn't think the same is you were partaking in frequent bareback full sex?
You're not comparing like with like - you're using personal experience as one measure and then anecdotal evidence as another.
Get real: wake up and smell the coffee boys... it's a risky activity and if you're doing one, you may as well be doing t'other.
