I'm a bit feminine at the core. How do I remedy this?

What does being feminine have to be with being bisexual? You’re getting gender identity and sexual orientation confused. Either way, you can’t deny who you are. It will always follow you and haunt. Be chill and accept it.

there's nothing wrong with that. we all have feminine and masculine sides.

Don't even try.
A man with some "feminity" is far more attractive than one with none.
Qualities like empathy, compassion and good communication skills
are the very best a man can have.
I don't know what traits at your core you perceive as fem.
Be true to yourself.

What do you mean by feminine? Do you listen to Brittany Spears? Do you cross dress? Do you walk like a runway model? Are you overly emotional?

Why fight it? Just be who you are
