Can he eat the kitty or nah?

So does any of y'all lovely ladies know of a spermicide that is edible? I hate condoms with everything in me. I tried birth control but they kept messing me up.. so I wanted to know if anyone found a spermicide that didn't taste weird or had an oder  if my man decideds to eat the 😻 or that won't poison him?  I know many of y'all are thinking why not put it in after he finishes but come on ladies it's not sexy to inject yourself after the mood has been set..
