Sorry to post a downer.
Sounds tragic, but every New Year's Eve, my wife and I negotiate the sex for the coming year.
It's worse than it sounds. About 10 years ago she stopped doing oral sex. After about 3 years we negotiated them back to one per year, but she generally reneged on that.
Generally, I beg her for things, she agrees to about 1 or 2 out of 5, reneges totally on one of those two, and does the other 1 for about two months before stopping.
This year, I'm going to ask for:
Any position other than missionary or girl-on-top (with her lying on top)
If she could undress fully (the clothes she keeps on are not lingerie or some kind of sex uniform - generally a worn out t-shirt and a cardigan or jumper)
If she could receive oral sex
If I could ejaculate on her stomach or breasts.
Of those, the last two will not happen, but they will be bargained away. She will probably agree to the first two, renege on the first before it happens,and the second will last until some time in March.
Happens every year - hence, it's a tradition.
