Intra uterine insemination

My husban and i have been ttc for two years. He gives himself so much pressure when its my fertile time we have decided that its best if he just wanks into a pot for me. Not romantic at all but he gets himself into such a state that he can not ejaculate when we have sex! I want to make sure it gets right into my uterus so was considering IUI. Has anyone done this at home?
