Thanks for the support, people! :)).
That's totally not my problem, quite the contrary. The environment I'm in sets very little pressure on me to behave in an aggressive hypermasculine fashion (I'll leave my opinion on the soccer and beer issue for another day, just to keep this short). My father is all but a model of such kind of masculinity and except for very brief outbursts of overcompensation when I was young, which I never internalized, I have never sought those things. I don't have overly high ambitions for myself, definitely not on the economic front (EU periphery simple middle-class lifestyle is enough for me, thanks). There have been times where I have strongly identified with a sort of grey, inert masculinity, defined by parsimony and emotional flatness, but even that is over now. This is not an expectation I'm afraid to break anymore.
So the point is that in a sense, any assertive display of femininity on my part feels capricious, superfluous. It's hard to rationalize the need for it in terms of personality traits, hobbies etc.. There is virtually nothing for me to break free from, no cultural tyrant to rise against, no narrative. Were not for the bunch of commands issued by the lower brain on how my body is supposed to look and behave (and -like- framed) in certain domains I would have no problem just being a 'soft male'. In fact it looks as an interesting and socially valuable role, one for which I have already a very comfortable set of social skills (how to be ironic about certain things, react to certain types of moves, etc). At least this is my interpretation.
[By the way, I don't see the whole issue as a problem of the self (false self, lack of self, etc.), but a problem for the self. The results of denying or mismanaging certain primal feelings might be disastrous for my life but by no means a treason to "myself". Swallowing an alien idea of what the self is does constitute one, though. Sorry, call me nihilist or whatever, but that's just me! :-p ]
