Hmm. I found that I could last _longer_ as I got older, through my 20s and 30s. But everybody's different. You may just be having trouble with the control muscles -- kegels might help, so does vitamin C, believe it or not. I'm in my late 40s now and find that I don't have the control I used to, to stop myself at the very edge of ejaculating. But C does help.

To follow another path, maybe you're getting more and more sensitive, or you and your partner are so good together that you're setting yourself off early? Well, there's always throwing a condom on -- kind of a wet blanket solution (literally), but if your problem is that you're revving up too fast, it'd cut back on sensation a little and make you last longer.

Of course when you get into your 40s, the real problem with endurance can be maintaining hardness for a long period of time, not ejaculating too soon. And that can be solved by extended foreplay and fantasy play -- really getting in the mood, in other words. (So yeah, you do learn more about sex as you get older, sometimes because it's a necessity!)
