I'm almost two years on T and my libido has shown no signs of calming down. Some people have high libidos, some don't. Everyone is pretty different in that regard. However, I think you could probably practice a bit more self control if you're avoiding friends and masturbating that much. That's quite excessive. Use all that time and energy for something more productive like a hobby, exercising, etc ¯\_(ツ)_/¯
