How do you guys deal with not feeling "man" enough? I guess I'm talking about those dysphoric periods that randomly hit us. I'm interested in this girl I know but I just feel inadequate hitting on her. She is beautiful and 100% straight. I've been on T for years and no one would guess I'm trans. I feel like any woman would eventually get bored and move on from me because I'm trans. Like they'll become sexually bored with me because I lack the part they desire. I've been feeling super dysphoric for a few days now. How do you guys cope with this?

Honestly, 99% of the time I feel like crap about not being man enough, I go out and buy some cool underwear. usually underwear, but maybe clothes, even just soap instead, something affirming. Something that I can say to myself "I am a man, so I will buy this manly thing."
If I can't go spend money at the time, then I usually draw. I know drawing isn't for everyone, but for me, drawing makes me happier almost all the time.

I listen to metal because it's a very masculine, mostly male dominated genre of music that I like and it makes me feel more manly.

I go to the gym, or (soon) will kick butt in martial arts.

Lift weights, do grip work, yard work, read Art of Manliness, remind myself that being born a cis man wouldn't have guaranteed me the things I consider myself lacking (whether that is a bigger penis, deeper voice, more traditionally "masculine" bone structure, or whatever).

I deal with dysphoria by doing pushups. My older brother is constantly giving me ->-bleeped-<- about not being man enough, easy for him with his muscles and chiseled, stubbed jawline. You just have to focus on the future. Be optimistic about what you want and how you can achieve it. I will look the way I want one day. Until then I want to do everything I can to help myself get there.

This is an interesting question for me because I don't really experience 'man enough' as related to my fysical aspects. I get fysical dysphoria (mostly toprelated and my voice brr) and deal with that by 1) reminding myself that these things will change sooner or later and 2) distracting myself or making myself feel better by working out or dressing nicely.
When I hear 'man enough' though I think about things like being respectfull and trustworthy... A 'real' Man to me is a decent guy who is helps people out and is kind and stuff like that and I struggle sometimes with feeling inadequate in that sense. Haven't figured out how to deal with that though, I find it hard to convince myself I can be a Man (instead of a guy). However I do meet a lot of cisguys that don't fall in that category either and I've met awesome transmen that absolutely fit that (very personal) defenition of feeling 'Man enough' so maybe one day...

having been tagged as resident man even as a girl, i don't really have any problem with this.
i'm manlier than most cis guys. and sillier.

it also helped to get some online friends who did a whole lot of telling me that i'm good enough just the way i am.
and meeting a girl who was more interested in how well i could tie her up. not that we ever got a chance to meet up, too long distances easily prevent that.
but i get this feeling that many girls are more interested in the not so physical aspects of a man.
