Low Sex Drive?

Ella
I'm 22 years old and have been dating my boyfriend for about five and a half months. At first in our relationship I had a crazy sex drive, which was awesome, but it's slowly dwindling off, almost to the point where it's non-existence. I'm dieting right now and I've heard that when you diet it can decrease your sex drive, has anyone else experienced this? Is there any way I can increase the drive?
