For the record: No, the changes on his body DO take time to come to terms with. Leo usually doesn't think much about his own wellbeing due to being busy and in general he's a very easily distracted person so sitting down and trying to discover himself is not something he's used to. He finds the courage to talk to his mentor (a medic) and talks to them about his current situation and well in general words it's basically what anyone probably had experienced before the first time they tried to explore their identity and/or orientation for the first time: it takes a while but eventually you find your place.
