The ones I love generally have bigger tits
Couldn't this apply to girls too?
Yeah, but I guess OP wants to show that guys do fall in love and know the difference.
You mean like how the girl I love exists and girls I've dated don't?
Ahem or lurp
That would make sense for anybody, because it would be a little weird if you didn't notice a big difference from the love of your life and a couple people you've gone out with.
