I hate for my period to be the reason why I cannot have sex. I offer him a blow job or anal... There are plenty of options
ha ha. there is no shame in saying you have your period. now you could take it up the ass or blow him if you wanted to make him happy. I say just tell him you have period and if he cant accept that, fuck it, cut him off, he's done, no more ass for him, you will see him beg for forgiveness...
