Yes we can. Just like the slogan. The prostate can spasm and cause ejaculation without an erection, though it's rare. The biological mechanisms that control erection and ejaculation, while often thought to essentially work together, don't have to. He may need to see a doctor, or perhaps he's getting distracted. Or, if he's an older gent he may be experiencing decreasing testosterone levels which is not your fault. There's lots of ways to address this but I would start with a doctor.
Yes, I have done it as well. But I wouldn't say that him losing his erection has anything to do with you turning him on any more, but maybe something that he or you should discuss with your doctor (s). Hope it all works out. :-)
