decrease the last few years, which I attribute to the ravages of age, but I've got 20 years on you. There is no way you should be losing sensitivity at 36, unless . . . .
I have several veteran Kgirl providers that I have dated outside a lot over the years, who sometimes share their observations of the the various customers they see. I have had several tell me that they often have a hard time with younger guys (your age and under) because they can't seem to cum except with a vigorous HJ. Their take after questioning some of them about it is that this is the free-internet-porn generation, and that these guys masterbate so much, it desensitizes their penis, so that they cannot get proper stimulation from BJ or intercourse to cum. They say I would be shocked at how many have to stop these other activities and finish with an intense HJ. The ones that aren't completely shot yet can still get off with a good pounding in doggie, which a cursory study of reviews of some of the younger guys seems to support. This is why many providers prefer the guys over 40 because they come from a non-porn generation and have not abused themselves into insensitivity, and so the sex can go a little slower, much more sensual with a lighter touch, and they can still get their pop without all the vigorous stimulation. Common sense is that older guys would take longer and have a harder time getting to the finish line, but that is not what these girls tell me. A man's grip is usually much more powerful than that of a woman, or her mouth, or her V-jay, so if you condition yourself to get off with a vigorous HJ by your own hand, it is going to be much harder with a woman. All of it made perfect sense to me. There are, of course, other explanations, and I think it is wise to get checked out by a urologist, just to make sure it isn't something more serious (I have never had a urologist ask how many women I have banged, so just tell them this has been happening lately), but as others have said on this thread, if you like to do it yourself, you need to lighten up . . . . . literally. I understand that it's reversable if its not from age
