Five things that keep your passion in bed alive

Are you in a relationship? If so, that's fantastic. Even more beautiful would be if this relationship were very passionate. Has passion been lacking in your bedroom? Let's take this stuff in order...

Dr. Justin Lehmiler organized a study of 40,000 people and managed to find out what are the five major differences between couples who always have a hot, passionate sex life and those that the flames of passion have long since been extinguished.

Those who continue to keep passion alive in bed are most likely to do these five very important things:

1. More preparation time is spent to enjoy.

2. They practice sexual communication, so they talk to each other about sex.

3. They practice oral sex.

4. They are happier with their relationship in general.

5. They practice changes in the sexual act.

Dr. Lehmiler explains that couples tend to be bored with sexual routines, but changes are those that reawaken interest in sex. The key to all this lies in a substance called dopamine. Dopamine is a neurotransmitter that directly relates to the brain pleasure center. It's a substance that makes us feel good. She gets excited by the changes or innovations that happen, so try to be creative when it comes to having a couple passion.
