Hi I have hair fetish I get attracted seeing grey hair and feel like colouring them to white, while doing intercourse with my wife I think colouring hair of a male or female and do intercourse will it affect my sperm count if I think anything else rather than female body in sex, please help I have lot of doubt ,i think about women body but sometimes use my fetish white hair colouring to do sex. Does sexual fantasy or preferences affect sperm count?
