WORLD:
Probably the most common problem for couples worldwide is lack of sex.
Is there a rule of thumb as to how many times you should have a happy relationship?
Ulrich Hoffmann:
Research says that you should open up the relationship when things don't go well in bed.
But I also find another study interesting.
It showed that having sex once a week instead of once a month makes you as happy as $ 50,000 more a year.
And for this it is worthwhile to talk to your partner about the problems or even better: straight to bed.

And who is actually unfaithful: men or women?
