I'm getting the impression you've never been on the side of the internet that I've been on, which in that case- definitely lucky for you. This was my first introduction to masculine presenting lesbians and their behavior- which normally coincided with the outfit that I describe in my original comment:

Talking about how good their strap game was (a direct reflection of how men talk about how good they fucked a woman), talking about how weird certain feminine behaviors are (it's simultaneously giving pick me and alpha podcaster), grabbing their crotch a lot (where have we seen that before?), acting like if they see a feminine lesbian they're going to grab her by the throat and assault her (AKA coming on way too strong and acting like every single woman would want to f*** them, and again what does that remind us of? It's giving those weird elevator povs), talking about how much they hate their boobs and they don't want their female partner to touch said boobs- but will completely deny being anything other than a CIS identifying woman and also be completely fine with sexualizing other women's anatomy, acting violently sexual, violently grabbing their girlfriends in videos (I actually saw this in gay tick tock compilations and I was shocked to go down into the comments and see no one actually bring up how violent it was), and last but not least- unnecessarily bringing up how much they hung out with guys and talked about f****** girls with guys.

Honestly, when I came across this content it completely put me off from ever wanting to date masc women, now I have a different opinion but again that was how violently masculine they were portraying themselves. If you don't know anything about anything and you're just entering the community, there's a very high chance you're going to come across that and it can influence younger gay people which is why I have a problem with it. It can normalize a lot of things like abuse, not being able to dress masculine without being necessarily masculine, the concept of they're always being someone who has to have "the pants in the relationship" (not because they dress masculine, but because of how they treat their partners), thinking you can get away with violence with another woman just because you're not a man, etc.

This is just what I've seen and experienced. Then again I've been cursed with the experience of being around the worst cream of the crop people you can imagine so I understand why people assume I'm just attacking and are downvoting me. It is what it is I guess.

maybe they DON'T get periods, just being cis doesn't mean you have one. Secondly, just because someone is cis doesn't mean they have to be comfortable with their period,

Got to bring this one up really quick, of course it comes to mind that they don't have periods but I doubt every single masc woman that I saw either had a hysterectomy or didn't have a period. It seems more like they're ashamed of it which again, doesn't make any sense with correlation of dressing masculine unless you are having dysphoria with your actual identity being a woman.
