I'm in my 60s and finding it increasingly hard to climax and ejaculate. (No problem with getting an erection btw, particularly if my GF's hands stray down there, and no problems urinating.) But when the time comes ... nothing happens. Occasionally I've had a completely dry orgasm when on my own, which is nice, but not the real deal. My GF also thought I was faking it once, which I wasn't.
Is this just something that happens with age?
