Do guys realize when...?

The qualities of sl*t and hot are not mutually exclusive, i.e. a sl*t can be totally hot, but not all hot girls are sluts. We see them [sluts] as a way to get off, not someone to have a serious relationship with. Only naive and weak minded guys (there are a lot of them) get tied down to a sl*t, especially the ones that trip over themselves to show how "sensitive" they. There is afterall a difference between being attuned to someones needs and kissing there ***.

It depends a bit on the situation.

Some guys are flattered when that sexy girl is interested in them and they become blind for her true nature, once they realize that it's not them in particular that she's showing interest for but guys in general, their interest for her often cools down a lot.

Other guys looks for sluts because the are looking for "toys" to use, not a real girlfriend to love and respect. They think the sluts are hot and interesting but they also know their value and that it's just a "thing" rather than that special "one":

Some guys have some sort of "hero" complex and they see the true nature of sluts but think that they can save the $lut from herself and turn her into something she's not. Just as some girls take on the bad guy thinking they can change him.

Guys are not stupid, once they realize that she's as $lut the know what it means too, some guys just need a little more time to see reality.
