I couldn't agree more with the gentleman that said getting older is ok.
The story by the previous gentleman is more than true. Getting older IS ok. I'm 68 now and although my wife passed away nearly six years ago, that hasn't stopped my sexual activity. As the pain of her death subsided I realized I was as horny as I ever was. I started masturbating when I was 13 and continued to masturbate even when my wife was alive and still do even though I have a girlfriend and we enjoy sex.
Getting older doesn't have to mean the end of your sex life. After I realized I was horny after my wife died, I began visiting porn sites and also discovered Solo Touch. I also discovered that I could no longer get a firm erection. Partially hard, yes. But not rock hard as before. I kind of chalked it up to getting older but I was determined that I didn't want to end the pleasure. I talked to my doctor and he gave me some Viagra. It helped but I still didn't get as hard as in the past.
When I met my girlfriend, the first few attempts at sex were disastrous. So the next doctors visit I asked to see a urologist. After a few tests, it was determined that I have poor circulation in my lower body. The urologist prescribed some injections that go into my cock (not as painful as it sounds) and within minutes it gets rock hard and stays that way for 3-4 hours! Even after I cum it stays hard till the injection wears off. One of these days I'm going to see how many times I can cum while it's hard. Also, the urologist taught me how to inject myself at home.
So...... to all the older men out there, don't just give up on sex and/or masturbation. There is hope and pleasure out there. Just look for it. By the way, the injections are on the expensive side and not covered by medicare, but that hasn't stopped me.
