let me give you all a womens point of view.
well a few days before, 2-3 days we tend to get excited easily
extra wet extra horny every thing also we want extra. now on the
day 1 of the period then its no go for many women some suffer
terrible cramps and the last thing we want is a screw. others get
really sore boobs . its so full and so sensitive now the last thing
we need is a lapping guy nibbling away. now after day 2 its kinda
settled and not the heaviest flow days.....now here is where fun
scomes in for some .. for the guys who like to ee red then bang
aways dudes..that is if she likes it... for some gals its day 3 n
day 4 thants fun... now ovualation period is not the same yet
constant for many..
basic advise is to observe yr women, for 2 months or more u will
know its her period i'm sure then slowly become adventurous
.....and enjoy it
cheers
