Sure, choose to ignore me if you wish. I am just adding in my story to show you that i was in the very same position as you at one point and things haven't turned out pretty. People on this forum encouraged me to try finasteride and even told me to carry on when i had watery semen and lost morning erections. I was so obsessed with my hair and this forum that i never stopped to think just how fucked up that is, you know?
Hair loss is devastating when it first starts happening. I lost my confidence and began to withdraw to a certain extent. I even questioned my future career and where i might study. The thing is though, deep down i always knew i was quite happy and i knew everything would be fine with time - i had a good life. Sure enough, once i met more girls and began to find myself again my confidence was back and hair loss was not an issue.
This time around, it is a whole different ball game. I can tell myself things will be OK and that my life is good but actually, it's not. 20 years old, almost completely impotent, unable to feel sexual pleasure/ arousal and the sleeping pattern of a 50 year old menopausal woman. I am sick of trying to sugar coat things. Finasteride is a horrible, horrible drug that is ruining thousands of lives worldwide. Who knows how many older men there are that have no idea.
Having said that, it does seem that permanent side effects are rare. I often find myself in denial and will probably never come to terms with it. I wish you the very best, and hopefully you can completely halt the hair loss if finasteride works for you.
