Sex, by nature is something we shy away from naturally.
People tend to blush when they are talking about their sex lives or avoid talking about sex with friends or family.
Our sex lives are something very private and so when we try to go past basic sex “partners being intimate” and start diving deep into other waters such as self pleasure, majority of people like to then bring religion, christianity to be exact into the mix, and ascertain that this is in fact a sin and should not be done if you are trying to be a holy version of yourself.
