What does it mean when a guy COMES TOO EARLY?

i had sex with this guy and it was the third time in 2 weeks and the first time we did it he came in about 1 or 2 minutes and last night he just got it in and came, like less than 10 seconds im not even kidding. and he apoligized like crazy but its okay. so i was wondering why this happened, its not that hes inexperienced, hes 23 and hes a total player he had like 50 gfs so its not that, i dont think its cuz he hadnt got laid in a while but idk. what else could affect it?
