It seems men never say, "I'm not in the mood" or "I'm too tired." It's not a secret that men and women have very different sex drives. Many relationships have been scarred, sometimes ruined, because of issues in the bedroom.

The most common complaint I hear from San Diego guys is that while they were in relationships, their girlfriends would refuse sex on a regular basis for a range of reasons. Individual sex drives are as different and unique as personalities. Men and women, however, do have drastic differences in the ways they function sexually.

The female sexual drive is constantly evolving. For women, any act of intimacy can be as pleasurable as the act of sex itself. One day we may be fiendishly in need, while the next day, the idea of sex may sound like an unwelcome chore. Unlike with men, a woman's sexual drive has the ability to exponentially decrease when she is affected by external factors such as stress, depression, and anxiety.

However, when the female brain is bogged down by daily life, an unexpected sensual experience may be just the endorphin boost you need. Discover three reasons why women say no, and why yes might be the better answer.

Stress
Try asking your partner for a foot rub or back massage; it might be just the stress release and physical intimacy you need. The endorphins released by any sort of physical contact will help you de-stress and get you in the mood.

Insecurity
If you are insecure about your appearance, try taking some extra steps to make yourself feel sexy. Lingerie or a new pair of hot stilettos can always perk up female spirits. If you are insecure with the person you are with, however, that is a bigger issue. Communication is key. Talk it out with your partner. What your relationship may be lacking is the physical intimacy that you are avoiding.

Lack of Romance
Fact: Women need to be romanced. A lot of women have an inability to function sexually without being in an appropriate mindset. Try engaging in a text or email flirtation with your partner during the day. This will add a sparks while building up anticipation.
