Here's the deal, reallynotsecure,
No need to apologize, but...Welcome to the world of real MEN, and not boys. This may be one of those signs that you're finally a grown-up 
.
A man's ability to ejaculate multiple times with a short refractory period declines with age. Let's be really clear and upfront about that. For some men, it happens in their early 30s. For others, it happens during andropause. Sometimes, there is a discernible quality in frequency of ejaculation, amount of ejaculate or simply ability to go on without shooting off after almost no stimulation. Finally, you're able to take your tiiiime and enjoy the action. That's what separates boys from men.
Now you are clearly not andropausal, so I wouldn't worry about that. But you may have to resort to the tricks of the game, just like you're doing now. Compensate, not release yourself for a longer time, etc.
As to ED, no, it's not a sign thereof. If it were ED, you have trouble getting it up the first time around. But sexual health is often a reflection of general health. If you're overweight or eat fast foods, smoke, drink alcohol, take drugs, stop exercising [a great testosterone-booster, folks] or get depressed, you bet yer willie that things will head south, no matter what age. Now, if you're "not the most fit person around" and you're only in your 30s, I'd do something about that. If you don't...well, then you will age faster, both sexually and generally speaking.

I dunno - I personally think the, shall we say, refraktory period increase after the first pop would be a thing that the ladies, quite frankly, would love! You know, remember the Pointer Sisters - "..I want a lover with a slow hand..."
Reallynotsecure, I'd say "celebrate your refractroy period" - don't fear it. In a tribal society, me thinks this facet would increase the size of your harem (along with lots trinkets).
BS
Yeah...it's an aging thing. I used to always be able to pop twice in my teens, with no problem at all. By the time I got to my 20s, it became more difficult. Now, up until this point of my life, all pops were via masturbation, since that was my only sexual outlet. After 25, I became sexually active, but by that time, age had taken its toll and two pops were rare.
I usually do 2-hr appointments and sometimes I have trouble doing a second cup. I think if I want to increase the chances of doing 2, I need to do the first one fairly qickly so I have plenty of time to recover. But even then I sometimes have trouble. It is frustrating and embarrassing, quite frankly.
Damn, I thought it was just me. Up to about 40, I was a 2 pop in 2 hours guy, but went downhill quickly after a nasty divorce. Not being sexually active, other than masturbation, for the next several years put a crimp in my abilities. When I began to hobby, a friend introduced me to a supplement, DHEA-M, which greatly increased the frequency and amount of my ejaculation. I was lovin' it. Unfortunately, I was diagnosed with prostate cancer at age 57, way too young. I told my urologist about the DHEA-M, and he became very upset. Seems that men with a higher testosterone level are more likely to develop the cancer. Stopped the supplement, survived the cancer, and at age 65 am a 1 pop a day guy, no matter what, or with who. The radiation treatment pretty much killed both nerve bundles beside the prostate and, without Cialis, nothing happens. With Cialis, the erection is not as firm as it once was, and the ejaculation is minimal if at all. But, the providers keep me happy, and I've learned a little cunnilingus goes a long way. My recommendations-lay off the supplements, and get a PSA blood test every year along with a 'finger wave'. My father did neither. He is no longer with us.
