I am a werewolf, I love being a werewolf but I wanna play as a Vampire Lord too while with Serana to enjoy myself as a vampire, but afterwards, I wish to quit being a Vampire and become a Werewolf again. I've researched and some say you have to finish the companions quest line and ask Aela the Huntress to turn you back into one again, but that she will do it only ONCE, others say to go back to the underforge and drink from the blood pillar again, and others say to get bitten by a wild werewolf.
So can someone who already knows the right way to do this help me please? I would really appreciate it.
