[Raimi Spider-Man] How does organic web-shooters Peter make some of his webs sticky and others not? He catches bad guys in big sticky spiderwebs, but he and MJ relax on a big web and it's not sticky at all.

Spiders have different types of silk, with different properties.  Some are sticky and some are not, some are elastic and some are not, etc.  They're produced by different glands inside the spider, and they each serve different purposes.  For example, a spider's web has "spokes" made of non-sticky silk, while the lines within the spokes are sticky.  

Similarly, we've seen Spider-Man produce different types of webbing from his wrists, including variations of sticky and non-sticky, as well as firing the webbing in small compact balls.  So it would appear Spidey also has some degree of control over what type of web he wants to secrete from his organic web shooters.
