I used it for over a year. It probably increased my ability to orgasm, and my nipples grew, becoming much more sensitive, but since it locks up free testosterone, I had some bone loss and started having back problems: I couldn't sit for long and had back pain. Stopping it relieved many of those symptoms. I'm now taking supplements to free up testosterone, and I have much more energy and less pain. Taking them has increased my libido, which I realize some here don't want. I'm rather enjoying it, though. Taking Dutasteride did alleviate some prostate problems I was having.
