The 32-year-old Glee actor, who plays Will Schuester in the musical series, said that he thinks women might find him intimidating.
He told The Mirror, 'I don't get as much female attention as you'd think, because I never go out. Maybe I'm unapproachable.
'I know what it takes to be a good boyfriend, time, first and foremost - to be there for someone and be involved in their life.
'But I'm so involved in what I'm doing. It's so rare that a moment like this happens in a person's career and I'm really trying to ride that wave.'
