Thanks to sites like NoFap and TRP I overcame the problem of not ejaculating or lasting too long while having sex with a girl. This was because of porn, gripping too hard and fapping frequently. Feels much better now.

Now sometimes is the other way around. I seem to be loaded of semen and come after a few minutes after the penetration, I enjoy it and shot a big load of it. But...

What should I do to last longer and keep enjoyning it.?

EDIT: Not erectile disfunction at all.
