If he try to ask for some mouth, hit him with that "nah I got a headache from my period, let's just cuddle."
He'll be sitting there with the

face watching Finding Nemo with me until I fall asleep.
this is the reason why you jokingly bring up these points before you ever make plans... ever since i heard cam say "hate chicks inviting you over, knowing they bleeding".......
i've made it a point to know that info ahead of time. the first time she's feeling bad or upset or mad or anything, just say "you must be on your period" don't even do it during this planning stage.. just make her made during the planning.. so you can say that... so she can say "no i'm not"...so you can say "i know, i was just playing boo"... then continue to make those plans....
if she says maybe it is... then make up the next excuse of why you can't see her... works every time
this and "you can't come over cause i don't want you thinking we fukking" are the two dumbest things women say.. i mean really.. aren't you in control. are you telling me if i come over you gotta fukk me.. cause i'm sure i'll be thinking we gonna fukk if i met you at 6 flags tomorrow... still don't mean you gotta do it.
and ladies if you need to make up a reason why you can't fukk, just so he'll come over and not try......then obviously your will power ain't too strong and your man don't give two fukks about nothing but ass.
