Nah, they'll only go that route if they want to kill the show.
Reedus has been doing interviews, and when they inevitably bring that up, he maintains (in so many words) that Daryl is hetero, but very awkward. Greg Nicotero said he just thinks Daryl is a virgin.
Personally I doubt that, because after all, he's Merle's little brother. Merle probably took him to a whorehouse when he came of age.
I think he and Carol were....making sure he was no virgin.
No member, Merle ran away and then did a stint in jail. The only sex Merle was getting was “Prison Gay.”
