As a result, when some people do encounter nudity, or sex, or thoughts of sex, their responses may be stronger, more negative, even difficult to control, than they would be otherwise. Nearly every social hangup about sex can be traced to the fact that our culture thinks of sex as bad or dirty, even evil. One result of this potential problem is that our sexual interactions with one another may often go wrong from the very start. In many relationships, sexual intimacy can be a major problem. There is either too much sex and too little intimacy, or too little sex and too much intimacy for anyone to feel particularly comfortable.
Sex becomes a goal in itself, the object of fixation, and sometimes even addiction.
Others develop sexual habits which are direspectful towards sex, which can be unhealthy psychologically, and lead to sexual experiences which are unfulling or unappealing. You may find this unusual, but historically, our culture's negative attitude towards sex is the exception, not the rule. Many cultures, both past and present, have not had the same misconceptions regarding sex. Sex is the source of life, and so in many cultures sex is associated with thoughts of a bountiful harvest or a hunting ground full of fauna. Since it is possible that any single sexual encounter can change one's life for the better or worse, and since there may be repercussions both good and bad, some cultures felt that sex must be respected.
