I am sure most of the more seasoned and health conscious members will have read this site already but felt this worth posting even if it is only news to a few more members.
I have searched the internet for info on this before but in the past always seemed to end up on the NHS website which is very vague and basically says ' low but some risk '.Today the search came up with this instead ;http://www.tht.org.uk/sexual-health/Improving-your-sexual-health/Oral-sex
Good information and a few useful tips.
Obviously difficult to assess the exact risks as oral usually takes place in combination with other sexual activities.
It does say that risk when performing RO is higher during the woman's period.
Some girls' willingness to receive oral but not perform OWO is a medically sound choice ( if that want to be extra careful ) going by the information.Conversely some punters willingness to give RO but avoid OWO on health grounds is misplaced if this is correct.
An unpleasant thought , and not discussed on the website link given , but with OWO may there be some risk from residual traces of the previous client if mouthwash has not been used or would the mouth's natural defences destroy it .Hopefully not something you would have to consider with a decent WG , but if someone is doing back to back bookings with no time to freshen up !
It is clear that risks from oral sex are a fraction of those involved with unprotected vaginal or anal sex.
I found it a very worthwhile read and so wanted to share.Apologies if it is already posted elsewhere , I forgot to check.
