married 20 years, 2 kids.
First 17 years (about), we had sex about 1-2 times per week for 3 weeks, then none during period.
Then, WHAM!, a few years ago, her libido finally kicked in and we sometimes have sex 5 times per week now. Those earlier years were kinda rough, because my libido has been high as long as I have been alive I think. It was the source of ALL our fights.
Lately though, life has been grand!
And question regarding period...she is often crazy horny during it and don't let a little messiness get in the way of our fun. I'm pretty obsessed with giving oral - so that week is very looooong to me.
