And attraction isn't entirely physical. Also nice try with the race baiting BS... /snicker
Physical attraction isn't the same thing as intimacy or sexual satisfaction or the like, hence the whole point of being quite shallow. If you never get past the physical attraction then your relationship was pretty much shit to begin with, full stop, especially if only visually appealing people could excite you in any way. /shrug
If you don't intend on marrying this is all moot, be shallow and frivolous all you like.
