Another scared teen

[SomeGermanDude]

Hi. My name is Alex and I'm 19 years old.
I am extremely worried about my hair since I noticed that my hairline might be recieding at the temples. But I can't really tell if that is really the case because I noticed it almost 2 years age and it didn't really change, yet I am very scared that I might go bald in the next years. It has already driven me into very bad depression.
Well the fact that my father (and his father) are both about NW6 is maybe the main reason for my fear. On my mothers side, nobody experienced hair loss.

I need some opinions to tell if my hair is already going away. If yes, I have already considered taking Finasteride, even after reading numerous horror stories online on how it can cause sexual dysfunctions, which wouldn't really bother me. It can't be that bad, right?
