Why are u crazy for sex?

I have seen so many profile where people are craving for sex and they have mentioned that they are physically unsatisfied; lonely etc. Basically to me people are craving for sex not because of pbysical unsatisfaction rather they are deprived of real love. If they would get real love
..they could be satisfied. Loneliness or lack of real like minded friend also making people more horny. Right love is the key. I am 35 years old male and live in dhaka.
