Sex, Making Love, F*cking; Is There A Difference?

Hmm... This one to me is kind of interesting. Some people feel that any time you engage in sexual intercourse, it falls into one category, sex. Others feel there is a difference in making love, having sex, and f*cking. Some may say making love is the act of having intercourse with emotions involved (it's slow and sensual), having sex is the act of intercourse with or without emotions (it can start off slow, then end fast or the other way around. It really is just the act of intercourse), and f*cking is just wild, animalistic intercourse (rough sex is usually associated with this). Some people say you can do all three variations of sexual intercourse with someone you love. Others say you should only make love to your significant other.  I think that when you really care about someone, communication is the key to keeping things on the right track and also the key to keeping your sex life enjoyable and healthy. Let your partner know what it is you'd like to have done. Talk about what you like and what you don't like... Do you think you can make love to just anyone? Do you think f*cking should be left for people you have no serious interest in? What do you think the differences  between the three variations of sex are? Do you believe there are any differences at all?
