Positive Mood

While having sex is obviously pleasurable physically, chemically research suggests that it can reduce depression and promote happy moods. And guess what the reason is – you may not believe it but it is exposure to semen. According to this theory, vaginal wall is very absorptive and the semen is believed to contain mood-elevating chemicals such as serotonin, prolactin, endorphins and oxytocin. In fact, according to a US research, it is reported that women who are not using condoms have fewer depressive symptoms and better mood than those who are using them.
