Thanks! Yeah, I was sitting there pondering 'but how does he know in the first place' and 'if he knew about it, surely a guy like Foggy would, y'know, not squander his jizz when it could do a lot of good in the world, even if it was embarrassing' and somehow wound up at donating jizz because way too much thought going into the magic healing cock.

(Also I wrote it with the idea in mind that this is because Foggy is a mutant and he's slightly weirded out by his mutation. Meanwhile the doctors who discovered his magical cock are like 'LET'S NOT TALK ABOUT THAT PART' because magical cure >>>> any mild mutant prejudice they might have, and also they like Foggy and don't want his life ruined.)
