Sexual urge is common with male and female after puberty. This hunger has to be satisfied. The other need is having children.
So it is necessary that sexual activity is the part of relationship between partners.Orgasm is ultimate need of both partners.Sexual activity balances needs of each other. It has many other mental as well as physical advantages.
I am 83.I am widower. I have no libido. I have no female friend. I learn from internet to solve other's problem. I am completely disinterested in sexual actiivity. my interest purely acedamic.
Sometimes I get like that. I actually don't have a problem with it. Whether good or bad, when you come right down to it, sex is overrated.
