I personally think people that have sexual isues are ones that have their estrogen levels surge a bit higher. estrogen to high in men causes shitload of problems for our johnsons.
Yeah, I think it's the estrogen too. I had problems on finasteride... but the WORST sides I had was when I tried 17a-estradiol, which is a type of estrogen. Holy sh*t. I felt like I wanted to curl up into a ball and die.
