libido

I’ve listened to some ex-vegans and some of them talked about losing their libido on a vegan diet. I remember one guy said that veganism was a cult and that because some don’t want to have children is therefore evil(which is nonsensical). But then I’ve heard Bobby’s Perspective’s video about Raw...

I am curious if anyone suffer on the beginning of vegan diet from side effects as a male. It has been 3 weeks and i feel i lost my libido and do not want to do anything as i do before going vegan. Any ideas.
