No, I don't think you're that at-all! ...especially when you consider all you've laid out here, as per / or reasons (as to) why: no male role-model growing up to model said behaviors after. And to reasonably be expected - to then, "Learn," - them from. . . these, 'skills.' So, it's okay! It's never to late to learn (if that's what you want to do: a job like that; if that is what you desire, just go sign up for one, or ask someone for some help, or a little guidance...) / My guess is that, a lot of those jobs you're talking about -- unless they're actual trades, where one does need some kind of training & or technical schooling & education: such as a carpenter, or an electrician (& even then, sometimes you can sign on & then become someone's apprentice in some situations, so it all just depends; on how you want to go about it~)* Long story longer! Don't compare yourself with others. Just focus on yourself. Because that's all that really matters. Let others think what they want. You can be & do whatever you want to be or do. It's all up to you. And that said, likewise, or consequently--you can also tell yourself consciously (which will have its way of seeping over in to the "un," or 'sub') that you cannot do these things. And you will likely be right on all fronts or accounts as well. If that/or those kinds of jobs are just simply not for you. Then try to find something with which your skills & talents match or pair up a little bit better for, or with. And in the absence of that - then ones in which are not so seemingly incredibly averse. Best regards!
