I've the exact problems with horny girls towards me who just wanted to be friends.

And like, if we're talking about sex, who do you think it hurts more to straight up say "I don't want to fuck you", men or women?

Just like the poster paints men, men are thought of as wanting to have sex with everything two-legged from chickens to ladders.

Nope.

And I'm a rather social dude, and Finns aren't particularly social to begin with, so I often enjoyed female company more than male if we weren't actually doing something (driving, playing, shooting) and just sitting and talking.

Because of the way I acted (best not get into that it'd be a novel or five), eventually they went, "uh, guess we'd just best be friends then", but it took a while for them to get to that point. And when they do, they don't actually mean it. Many think they do. A couple have. Most have not. Those who only think they mean it or even just say it in a hollow sort of way, they're basically just saying "oh, well, I guess I should get over you then".

Like yes, please do, and try to do it in a way that you could still be my friend. But usually it kills... something.

But I can't straight up tell a girl "I understand you're into me, but I'm sorry, I'm not into you, can we just be friends?

Even just reading that — no matter if you don't know what sort of a person I am — you probably thought "what an arrogant dick" It might sound neutral on text, but idk perhaps it's a language barrier, as that seems polite enough to me now that I write it in English, but it sounds so rude in my accent in Finnish. Or perhaps it's a localised issue. I haven't lived abroad unfortunately.
