Multiple orgasms.. For a guy.?

Lauren
Okay so I always heard that guys can't have multiple orgasms and every other guy I've slept with gets soft after cumming the first time but this guy I sleep with now will cum and immediately stick it back in like he never goes soft. Is this normal? He also barely ejaculates anything. I wonder if he has low sperm count or something. Have y'all experienced this before? What do y'all think?
