Extended pleasure condoms working a little too well?

So long story short, for various reasons I was having little to no sex in my life up until the last couple of months.

Now, I have the opportunity to do so, but I ran into the issue, that I could not get hard at all. Went home, got rock hard for porn, realized what was the issue.
Dropped porn all together, now I have no problem getting hard.

Next problem was that I’m so excited and horny during sex, that sometimes I cum in the first 30 seconds, on better days in 2-3 minutes. Found these extended pleasure condoms to solve/help with this.

I have to say, they work well. Very well. Maybe even a little too well.
For the first time, maybe ever, I felt like I had the power to do anything, since I did not have to worry about randomly cumming in a couple of strokes.
For the first 10 minutes at least, after which I ran out of cardio, got totally limp, and felt like I just ran a marathon.
After 5-10 minutes of intermission, I’m able to continue, but the issue remains.
With regular condoms, I cum in seconds. With delaying ones, I’m unable to do so at all.
Now, the obvious solution would be to improve cardio, which I’m working on, but I would appreciate a middle ground. Something, that helps me last longer, but does not make me numb to the point where I can’t cum anymore. Also, it would be nice not to have to depend on a product to have a somewhat normal sexual life.

Any help would be appreciated.
