Forgive my ignorance, but it would seem that owo must be practically 100% safe as 95% of girls and punters provide it / avail of it with no (apparent) repercussions? If not, I'm still surprised, given this intimate contact, that nobody seems in the slightest bit concerned, even though there is pre-cum , possible CIM etc. Sex without a condom is a no brainer, so is it something in terms of the mouths defences that make OWO such a safe, low level risk? Apologies for appearing sanctimonious, its not intended.
