I like titties. They're versatile. You can do things with them that will drive the majority of women out of their mind like few other things. For most vanilla women, its the closest thing to a fetish spot. I've caused orgasms just from nipple play (not too hard if you find the right girl). They sort of stick out, and are prominent. They can really grab your attention. Or they can hurt you if a pair of bigguns whip around too fast. It's the easiest erogenous zone to access, and can be done accidentally. It's also fun to play with tittes in public, cause it causes that wonderful playful social discomfort in the girl. On a less playful note, some scientist types believe that men like healthy hooters because it shows virility and the ability to bear strong sons, etc. They like to take the fun out of stuff.
All that being said, it's far from my favorite part. I just find that by and large most women would rather have their breasteses played with for pure sexual gratification than any other non-genital area. My wife likes em more than I do.
I think for most guys it comes down to something simple-ish. I think every human being is born with what is commonly called a fetish. It's undefined at first. But for those of us considered to have a fetish, it's feet or nails or something. For most people, it's a breast fetish. I think we overuse fetish and under use the word simultaneiusly. If a guy prefers feet to breasts, he's said to have a fetish. Erroneous, I say. I say it's just a prefference for one part over another. Just like the difference between leg men and breast men.
I prefer to use fetish in more of an activity terminology. Tickling fetish, pain fetish, etc. I think any "fetish" revolving around a body part is just our natural preference for some part of the human body that everyone has.
So for most guys, it's probably a breast "fetish".
And like they said in the Aviator "Who don't like titties?".
