Don't judge a mug by it's whiskers. For years, Wes was a lothario. A pretty common trait for both demons, and satyrs. Lots of sex usually results in bastard children, and he has a few. There are two sons, and a daughter he is hoping to have cast at theyearspassed. As their mutt status is a bit complicated, I'd rather just discus it in comments.
Also, he fronts a rock band, and needs band members. They can be anything, vampire, demon, were, human, etc. It doesn't matter. They just need to be able to rock out, and put up with grumpy here.
