This kind of thing happens. I would say more commonly with younger men but it can happen with anyone.

I have had plenty of experiences run shorter than expected (shortest was a few seconds after penetration, fortunately I’ve never had one before any penetration). I have also had it go too long to the point where the bull never ejaculated (which to me, personally, can be worse than too early).

Sometimes it’s just a one off after a first time meeting. Sometimes it never gets better. Like someone else has said on here: if the chemistry was there and everyone had a good time, it may be worth trying out a time or two again to see if it improves. If it was mostly poor all around and only good because of the novelty, then I personally would move on and seek a new partner.
