Oh yes.
Unfortunately, Japan is a rather bra-obsessed country. Even though the majority of women here are in the A-B cup range, going without a bra is almost unheard of (for women, that is. The guys can get away wth sometimes).
My wife wears a pretty thick bra when she goes out, but when she gets home from work she prefers to just wear a T-shirt. The view is usually quite good and I make sure to let her know just how wonderful I think it is.
That strikes me as a little odd. I can see it being a reason to notice you but, while it’s a lovely sight, if it’s a “major factor” in their being attracted to you, it sounds pretty shallow. I guess after a while they get possessive? Like the guys who are attracted to women who dress provocatively, but then want them to change their style, once they’re together. It sounds even sillier, in your case, since there’s nothing you can do about it. But, they must be asociating it with arousal.
I think its because some men when they are single will ogle the ladies along with other men, but when they get in a relationship with that woman, they feel uncomfortable when other men are doing it. Maybe its possessiveness, maybe its just putting it into a different prespective for them.
OK - “major factor” was a bit strong - but most mentioned sometime early in the relationship that they had noticed that and liked it. A lot. In general, I am not what I would consider “very attractive”. I have my strong points, I am very enticing to those whose tastes run in my area, but I am not undeniably gorgeous.
Let’s take my most recent relationship. Met at work. Flirted extensively prior to getting involved. During that time period, he loved to point out when I was “cold”. Snap to 2 years later - he complains that I made a poor bra choice because they have been sticking out all day and I am going to put someone’s eye out. I put on a sweater, he says, “much better.” He was somewhat possessive and I am quite sure Incubus is pretty close to the reason. It is either that or he didn’t want to be distracted at work? I don’t know.
Women with inverted nipples get a little bit more attention from me cause Im trying to figure out where they are.
That’s pretty funny. I’d always figured that there would just be little divots in their clothing where their nipples should be 
From watching Friends, I learned this means your wife is a lesbian and will soon be leaving you for a woman. Sorry to break it to you like this.
I feel the need to post in the name of men who aren’t lead around by their “downstairs brain”. I could really care less if her head lights are showing or not. What are you, a pre-teen? Never seen uncovered breasts before??
Sure. I saw a pair, last night. Doesn’t mean I never want to see any more.
Incubus and Chrisk72, you’re probably right, but it makes me wonder how these guys are going to react when they eventually get some poor woman pregnant. That’s a far more definite sign of sexuality. Are they going to lock her in the house for the duration?
And, Chrisk72, you may have “strong points”, but I defy you to put my eye out with them. In fact, I challenge you to do so!
