A penis that has recently been inside the vagina of a menstruating woman, and unwashed since. If the woman then goes down on said penis, she is sucking on an "iron popsicle."
My boyfriend and I had sex while i was on my period. Later when we went to bed i decided to suck on his penis a bit without thinking of the period-sex we had earlier and had myself an iron popsicle.
