Maybe, but I don't think so. The difference is, before I used to do what's called edging. That when you get yourself as close as possible to cuming and then stay there as long as possible before coming. I've always been good with stamina, so this would probably last between 20-30 min depending on how much time was at hand and when I was willing to let myself cum. Now, I really can't edge any more. If I'm close to cuming and don't stop, I'm going to cum if I want to or not. Generally now, I last 30-40 min. The good part is that I can last 30 min without trying to last 30 min. I like that because I can let myself be more in the moment without thinking about how close I am to cuming. The flip side is that, I really have no control over when I cum. I physically can't have a five min quickly any more. I can't cum from slow sex any more, and with the loss of sensitivity, I really don't enjoy that much either. Before, I have had times were I lasted just as long if not longer then I do now, and I did cum harder, but this still feels a little more intense and I've never shot off loads as far as I do now. I think it's also a matter of needing so much more intense simulation to cum. When I'd edge, I'd build up, slow down, and vary the past based on how built up I was. Now, sex is usually at a harder/faster pase. I think that's more what it is, prolonged simulation, hard and hast, directly on the head. It may also be because the head is the main focus now. I know with jacking off, before the focus was on getting in a full range of motion and changing speeds. Now, I'm circumcised tight as a drum. The skin has very little mobility and because of that I really don't feel much from the shaft. Now when I jack off, it's lube and a lot of vigorous movements centered on the head. I think the change in focus may also factor into it.
