Cum stains in shorts?

Is it possible for men to leak it like we have discharge? My husband has small amounts of it in his shorts I was just throwing in the wash…we haven’t been intimate since laundry got done a few days ago so I know it’s not from us. I know we’ve had some cuddling sessions the last two nights where he’s gotten an erection, but we didn’t do anything (to my knowledge) so could it possibly just be from that? I confronted him like a crazy woman already but just trying to see if there’s any innocent answer to it…
