Why are humans,for that matter all living beings so much interested in having Sex?
-
Sex is a very costly activity, and not just financially in terms of flowers, chcolates, dinners and cinema tickets. The energy investment in sex and reproduction is huge, as is the risk to a female's health. (In parts of Africa the maternal mortality rate associated with childbirth is about 25%).
So for such high costs there must be a payoff and a motivation. Genetically we're programmed to want to reproduce, and the act associated with reproduction is extremely pleasurable. This has to be the case because if we didn't reproduce we'd all die out!

Great answer Chris, as always. So, in a nutshell, we humans are interested in sex because it's pleasurable.
I do wish more young people (teenagers) would realize what you said. That all of this extreme pleasure can, and often does come with great costs. Would you go so far to say that everytime a woman has a child, she is risking her life?
