I've never had a strong father figure growing up, I won't get into it but I was raised by women. In school I was the lowest on the totem pole and picked on a lot. I've improved a lot since then but I still feel I'm a weak man. Does being manly just come with age or will I always be like this?

I was wondering what sort of tips you guys can offer so I can become more masculine or manly?

I'm not competent with many things. I'm not handy. I have soft hands and I don't know how to fix things. I don't have many hobbies. I'm a bit indecisive sometime because I like to weigh my options. I'm bad at sports, yes all of them. I'm really weak physically and my physical size isn't big, and that's always weighed on me. To give you an idea my gf once described my wrists as "dainty". I just feel like a bitch.

I want to feel masculine and I'd like to learn how to become more manly. I'm not aggressive enough. I'm not competitive at ALL(because I was always the weakest link). I Just want to become a better man.

If you read this and your instinct is to tell me to be myself or say something nice, or that it's alright, I thank you but I'm looking for solid advice on how to better myself and be a better man. Maybe I have issues but I'd always like to be on a path of self improvement.

Edit: Thanks for everyone's great replies. I'm not particularly looking on how to do A or B activity in particular. I just want to learn to stop being a bitch, but masculinity is not something tangible so my descriptions were an attempt, it's an essence and a vibe, and I have no idea what to tangibly do to be manly.
