What it really comes down to is that you're too weak to be yourself.
This might hurt to hear, but you're a coward if you let gender roles stop you from enjoying something.
I sincerely recommend reading some theory on gender. Gender Trouble by Judith Butler is a surprisingly approachable introduction to the subject, despite not being written as such.
The "opposite sex" isn't a monolithic bloc.
You could police your identity to make yourself attractive to someone that you need to hide yourself from for the rest of your life, but it's a tremendous waste of energy. Find yourself an anime girlfriend.
it's already not so attractive to watch TV and even less attractive to watch anime or other children stuff on it.
