Bummed TMI

Do guys ever have some leftover semen come out like after sex? We just had sex on my day of ovulation and I was on top, he came in me, I know when he finishes because he said he’s coming and moans and everything. And I stayed on top of him for awhile right afterwards but when I got off, he said “oh I still have some coming out of me” I’m worried none even got in me and it all came out after I got off or something
