There are so many threads on here about lack of sex, or too much, or the wrong type, or with the wrong person - and it's very sad.
Another, more male orientated, forum I frequent has similar tales of woe.
Ever heard of Reddit?, it's called the front page of the internet. It's mainly for younger people. but there are sub=reddits for conversations about pretty much anything, and there's one giving advice, from both genders, called - dead bedrooms.
Some might benefit from checking it out, I hope you find a trip over there worthwhile;
