Barry definitely makes a very good Little Black Dress when it comes to pairings! And I love that idea - I can just picture Len being all snarky to cover up that he's a little embarrassed and Barry so shocked, "You're what?" and Len does a put-upon sigh and eye roll, all "Don't make a big deal out of it, it's nothing." And then Barry's really tentative and gentle with him and Len acts like he hates being treated with kid gloves but he actually loves it and in the end just totally falls apart when Barry fucks him.

And ooh yes, I kind of thought for Hannigram you might say Will was the virgin but that's so much better with Hannibal changing his mind about sex because of the way he feels about Will, that would be gorgeous.
