Finpecia day one

[t1111]

Hi

I've taken 1 finpecia (generic propecia) 1mg tablet two days ago. I've never taken this kind or any similar medication before. I've never had problems with erections or ejaculation before but ever since taking this one pill I cannot get an erection to last and it is absolutely different to how it normally is including watering semen and soft erections. I'm not imagining this, how long until the side effects reduce back to normal? I'm not planning on taking any more pills, after just taking one pill the side effects on my downstairs has been huge. I'm healthy 22 year old without prior problems down there.
