Thank you for the helpful answers! My other question is if my girlfriend and I will be more attracted to one another when my t levels are normal?
Maybe. It can depend on many factors.
Also, what's the "Birth control" part standing for? Birth control pils can change women's taste in men if that ain't a myth.
So it can be pretty effective if she wasn't taking them before you met.
Are you attracted to her now? If not, are you attracted to other girls? If not, are you attracted to anybody?
Do you watch porn, by the way? If you do - quit right now. It does affect your performance (lowers the drive due to insufficient levels of dopamine). Contrary to popular belief, porn makes you bad in bed.
If your girlfriend is not attracted to you - read my other answer.
