Biology: Why do we have the urge to have sex? What affects the libido of a person?

Many people have sex due to many reasons, for example, some have sex for physical reasons ("I was curious about sex"), while others have sex with a goal in mind (" I wanted to break up a relationship"). This blog post will zero in on the topic of why people have the urge to have sex. To begin, people have the urge to have sex due to this drive called "Libido" which is also the sexual instinct or sexual drive. Different people have different levels of Libido for both men and women and the higher the Libido, the more a person desires for sex. So, what are factors which affect the Libido? (This post will zoom in on why females have the urge to have sex).

Firstly, this sexual drive is affected by minor factors like relationship issues where if the relationship of a man and a woman is not good, the libido for both of them may be low. Also, it is affected by psychological issues like fatigue. It is said that fatigue can decrease a man's sex drive which is caused by factors like illness or even sleep deprived. Psychological issues also cover experience of sexual assault or abuse which leads to the mindset of a person resist sex.

However, the key point on why women have the urge to have sex, lies in the testosterone and menstrual cycle of the woman. Several days before ovulation, it is said that a woman will experience a heightened sexual desire. This cycle has also been associated with changes in a woman's testosterone levels during the menstrual cycle. According to a health journalist,Gabrielle Lichterman, testosterone levels have a direct impact on the sexual drive of a woman as it rise on around the 24th day of a woman's menstrual cycle until ovulation on around the 14th day of the next cycle. Coincidentally, she says that the woman's desire for sex increase consistently during this particular period of time. After ovulation, the testosterone level is the lowest causing women to experience less interest in sex. During this period of time, progesterone levels also increase, resulting in a woman experiencing difficulty achieving orgasm. Although the last days of the menstrual cycle have a constant testosterone level, a woman's sexual drive may increase due to the thickening of the uterine lining which stimulates nerve endings and makes a woman feel aroused.

Reflections:
I decided to do a research on this topic as I feel that many teenagers are always doing the "wrong" thing, engaging in underage sex and this issue seemed to worsen every year. I wonder what causes human beings to want to have this urge to have sex and thus did a detailed research on this topic. Based on my findings, it seems that this sexual drive occurs due to many reasons and it has definitely raised my knowledge on the issue of sex and not just say because people have the urge to have sex so they do it. This topic is also connected to what I am currently learning in school- sexual reproduction. It seems that this urge to have sex for women is also caused by the menstrual cycle of a woman. This research has definitely matured my view on the topic of sex!
