Luis, you may not be a PE vet (at least yet), but your advice is dead on with mine.
Can you double your PE efforts? Absolutely.
Should you? No way. Just because you can
try to bench press 500 lbs doesn't mean you should. Similarly, just because you have the time to PE twice a day doesn't mean you should. Your penis, as luis point out, needs time to heal and grow. This most likely has something to do with
the penis being part muscle.
