After my first two years in college I have noticed a significant decrease in my confidence and that is mainly because my sex drive is lower Than it was before. I have always had a hard time building muscle and my testosterone was 400 when I went to the doctor a couple months ago. My main question is......is this just a phase and will I get my sex drive back? It kills me sometimes because it was so much better a year ago. I need some input so hopefully u guys could help out, I would appreciate some serious answers. And if your wondering, yes I have seen a doctor and he said everything was okay. I'm also developed and have adult features so it's not like I have a deficiency. My sex drive is very on and off. Some days I feel like I'm fine and everything is normal but then it crashes a few days later. This has become a problem in my life that has me thinking about it constantly.
