So I'm in a relationship with an vegan and I've taken on her habits of consuming soy. I notice that although I want to have sex with her all the time, I am starting to feel insecure and needy. I don't have the self confidence that I usually exude.

I don't want to blame Soy as a culprit but could it be having feminizing effects? The thing is theres scientifically one group of people saying it does and one that says its beneficial for test. I notice my girlfriend is very explosive and irrational at times, but as I am body building I am taking in alot of soy for protein so I was wondering if it is having an effect on my mood?
