Being stereotypically feminine is devalued by society. Feminists therefore assert their femininity and the equality of that to masculinity. So far so good. But I am not stereotypically feminine.
Curious what you mean by this? When I think "feminist" the image of a very "feminine" woman rarely comes to mind - quite the opposite in fact! The "traditional" idea of what feminists looks like is actually something used to ridicule them isn't it? Deriding them as a bunch of ugly/butch/lesbians who are only feminists as no man would want them 
I find it curious just that you feel excluded from it on the basis of not being "feminine".
By this I mean things like hair, make up, grooming, enjoying shopping, wearing dresses etc. Then also more seriously female professions and care roles being paid less than male ones. And in literature (my particular area of interest), "ballsy" (a sexually pejorative term for starters) female characters being valued over gentler ones. There's a lot of interesting analysis of the reception of Arya vs Sansa in GoT as an example of feminine characters being devalued whilst boyish ones are praised (see also Susan vs Lucy in Narnia).
I don't like these things much myself and don't bother with them, but there's a lot of cultural devaluing of these things as frivolous and unimportant because they're "wimmins things", or that feminity is inherently separate and weaker than masculinity.
Obviously this is wrong, and I agree with it being challenged (in my own written works, I've worked hard at a range of female characters).
Further, my experience (to an extent) is that some feminists take it further by asserting that women who DON'T appear to be fitting in with that mode of femininity are either wrong to be different, or are men posing as women. This is my issue with some of the debate online, of a particular vein of feminism that shuts down feminist debate.
(ironically, I think this goes further towards an old theory of gender that believed women MUST be one way, and men MUST be another, which is less old than you think, but this post is already getting long, so here's a link www.google.com/amp/s/www.latimes.com/archives/la-xpm-1990-11-04-bk-5243-story.html%3f_amp=true)
I'm not sure if you expect me to do a thread trawl for when I've experienced this, but I hope you don't think I'm lying or blaming women.
