Old Man Still Cums

Yes, I am 78 years old but I still enjoy that wonderful feeling of climax. I am married, but my wife has not wanted any kind of sexual activity for about 25 years. So my main sexual relief is with my hand. I have also been with a few other women through the years, but I guess because of a feeling of guilt I have not been able to get an erection and so was not able to fuck. I have been with some men also, but my main sex has been jacking off.
In the last several years, because of my erection problem, I have found that almost all the time if I can find a good porn video online, I can get hard. I have also found that most times, even without a full erection I can still cum. In fact this morning early, while my wife was still asleep , I found a video of a woman giving a man a massage and ending by her jacking him off and him cumming. Of course I was working on my cock and just after he shot his load, I was able to cum. I don't really shoot it out like I used to and there is not as much as there used to be, but it still feels just as good and gives that relief.
I used to jackoff at least two or three times every week, but now about once per week takes care of my needs.
I just wish at least one more time I could get hard enough with a woman to experience that wonderful feeling of slowly sliding my cock inside a warm, wet pussy and pumping in and out until I cum inside. Oh, well, I'll take what I can enjoy and just "fuck" my hand.
