I have alternated between cbj and bbbj in the past years. All SPs I have asked told me they prefer cbj as is it more reasonable in the context. Bbbj is not very risky but there is still a risk. I enjoy the peace of mind more then the bbbj plus I can always CICIM (in condom).
There are a few that do not like cbj but they are rare. There are a lot of indies that advertise « safe gfe » which means cbj.
