Expert Q & A Answers About inflamed prostate and ejaculation

Now that I’m 64, I only ejaculate about half the time when I have sex. What’s going on?

I’m a 64-year-old male in very good physical condition, but I don’t seem to ejaculate consistently. I have sex about 3-4 times per week. I’ll have sex and be able to ejaculate one week and then nothing the next week. I can’t figure it out. What’s going on?
