I never DAYT but happy to receive BBBJ. There is risks but I hope the risk is very small.
A few years ago I was offered BBFS as she noticed I was going soft with the condom. I asked her firmly if she has been tested recently and free from any disease. She firmly replied yes, I caved and tried BBFS for once if my life.
NEVER again. The aftermath of receiving BBFS is not worth it, worry about catching something, getting tested, the other half finding out etc.
