I'm not the 'girly' girl type. I love marvel. A big fan of harry potter. I also play a lot of pc games. And yes, I love watching soccer game. Many guys hang out with me but they don't see me as a girl. Do I have to change so that I can, at least, have a bf after a looooooooong time being single?

Depends upon you...

Welcome to M2...

Hmm, I am not the 'boy' type of a boy, love cooking for example, and don't like cars, motorsport, etc. So what, gender stereotypes are like other stereotypes ... rubbish

There's a chance that one of the 'boys' you currently know is interested in being your BF. Perhaps you should bring conversations around to that subject and watch their reactions.
Look for the ones that always want to be around you, laugh at your funnies and get concerned when you are sad. They may just see you as unapproachable or not interested.

I think the best thing you could do is just be yourself, after all, its your life you're living.
If he really likes you being you and you really like him being him, what more do you really need?

In my opinion, the worst thing you can do is create a persona that is not you, just to be liked. Lies are a lot of work to maintain. Its much easier and less stressful to just be yourself.

Honey just be you don't change who you are just to impress.... the right one will come along

listen to these two ^^^

Such a smart man

Absolutely not! Never change who you are for...anyone. Regardless.

If some guys don't like it, then it wasn't meant to be. They have to accept you for who you are like they expect you to accept them for who they are.

Be yourself, everyone else is taken, Oscar Wilde.

You don't have to change yourself in the sense of stopping doing these things you love.
But... It might be helpful if you learn to be feminine within these (=your own) perimeters. You can play computer games, watch soccer, and still be girly & feminine. Just a glance, a smile and so on.
Being considered "feminine" and 'relationship material" is not about what you do, likely more about what you don't do.
The fact that you like these so called 'masculine' things doesn't mean you have to behave like a bloke. Unless that's what you want. Then you'll likely attract feminine energy men. Whatever floats your boat.
