Precum

Question ladies, so my man doesn’t cum. He does but it takes him a very long time and due to his anxiety he just hasn’t been able to while having sex. He doesn’t masturbate ever because he doesn’t feel the need or want to. So my question is he precums like crazy. Throughout our whole sex session and it’s quite a bit. This may sound stupid but since he doesn’t cum or masturbate there aren’t sperm in his Precum correct? I’ve seen mixed things about this. Thanks!
