I'm 23, healthy and active. I have a full set of hair but 8 months ago I notice serious thinking/baldness on crown(small spot) and small recession in front. I've been given Propecia along with foam 5% rogaine. Will I likely have erectile dysfunction or not be able to orgasm or whatever the sexual side affects are? Does it happen to every man taking it?? Just a little worried but the again I don't want to bald like my dad did
