People which have obesity, can have it because of hormonal dysfunction. And hormonal dysfunction gives impotence. Easy. On the other hand, the guy which quoted my message, also can be right. Because sometimes it's just stress. Or intoxication. It can be a result of bad habits also. BTW, not so long ago my cousin (he's 35 y.o) told me that he has this problem. No wonder why - he's an alcoholic, lol. He asked for my help, I asked my friends for advice and one of them told me about Generic Cialis pills. I told my cousin to use it and it helped him. I guess this stuff is good.
