it's normal for one's sexual desire to wane after one or two years of dating, said Andrea Seiferth, a psychologist who works as a couple's therapist in Hamburg. A cocktail of hormones plays a big role in this , said Seiferth. They increase our sex drive at the start of a relationship but as relationships progress, a hormone called oxytocin, which fosters social bonding, becomes more pronounced.
Trust isn't just good manners or playing nice. It's something we live on, whether we realize it or not. We use it every time we open up to someone, every time we take a chance that they'll show up, follow through, or just treat us right.
