@SmolPatao no, it is just that you might find less common ground to talk with men about, so you might be nervous because you just don't know what to say, or it could be you just don't talk with men much, so you might be unsure how to act with them. I don't think that makes you a femminist, because being femmenist and hating / disliking men are two different matters all together.
I find that quarantine has made me rusty with talking to people in general and I have trouble talking to people quite often, so I might be assuming you are experiencing something similar to me.
