If U must know, it feels x-tra shiok simply because of the very,
very slick feel and x-tra lubrication that is present. If the sight
of b***d turns u off, don't look down there when doing it! Of
course, use extra towels to line the surface her bum rests on or do
it doggie style. As for her, sex during periods is ACTUALLY a LOT
more enjoyable because there's less pain from all the xtra
lubrication and the increase of hormone levels. Talk to the
ger...it's like discussing other intimate issues and sharing if
there are mental blocks. U find that it will bring u closer
together and making love, period or not will be much, much more
enjoyable for the both of you.
GOOD LUCK!
