20His Healthy activites
Jax Teller does well with the ladies. Really well. His choice of relationships, however, are not always the smartest. Sure, Tara is a fairly nice girl all things considered, but the rest of his conquests are not exactly the classiest bunch. Among Jax’s many romantic pairings in the series, there
have been biker girls, addicts, and almost his half-sister. At no point does it really seem like Jax is using safe methods.
Seeing as Tara is a medical professional (and a very practical person in general) and the fact that she and Jax had a surprise pregnancy, it’s safe to assume that they were regularly unprotected. Tara wouldn’t have likely done that if Jax weren’t perfectly healthy.
