How many orgasms can a man have in a row?

scientificaly, man can have orgasm in every 45mins,coz within 45mins new sperms are made in testis.so,its very easy to have orgasms after 45mins.

But some complications will come if someone try this,like,tiring,itching on penis etc.from personal experience,i had 6 orgasm within 8hrs with my gf
