Well, God apparently has changed his mind many times in the areas of wearing mixed-fiber clothing, breeding spotted cattle, and disallowing Mormon men to take multiple wives, so I see no reason why he couldn't change his mind about a lot of other things.

Because it feels good.
Duh.
The fact that humans engage in and desire sex SO much more than required for reproduction (including females who are interested even when they are not fertile), indicates that sexual activity is important for bonding and social reasons.
