This is why.

This is what happens when immature males see females of their own age not as people, but as a means to an end.
Be it a social status thing of having a girlfriend, being in charge, or just exercising the overactive sex imagination they have.

Teenage boys are afraid of interacting with real girls.
Scary thought it is, that they may have feelings, moods, opinions. Very confusing!

They are 10 years off realizing girls are real humans too.
15, now that this is a thing to distract personal development into adulthood.

How do I know all this?
Well . . . being an introspective type of old guy in his 70s, I've spent a lot of time analysing what I did and why I did the things I did when younger.
The old me doesn't really like the young me.
But that is part of the human condition, the burden of self awareness.

I can't believe how close I came to being an incel (long before there was a word for it).

I got straightened out, thank goodness. But it was a close thing there for a while...
