Also, if I use the word love, like, by these word(s), I mainly mean: finding sexually attractive
Then don't say "love". Say "find sexually attractive". Why introduce terminology that you redefine for your question when that terminology has a lot of other baggage attached?
"Do women find the male chest sexually attractive?" seems like a reasonable question to me; it could be answered empirically with a survey approach asking women about physical traits they find attractive. You'd be mistaken to take any of these results as universal or describing any individual, of course. That said, I don't think it belongs on Biology because it doesn't ask about any underlying biology, but I feel it could fit on Psychology.
However, your question has a lot of other rambling junk in it. You go on and on about "hot girls" in movies, personal anecdotes, etc. Why? This is not helpful, it has nothing to do with your core question.
The majority of your question focuses on men's attraction to women's breasts; while it may be reasonable to establish this to ground your question, none of the elaboration is necessary or relevant to the core question. Neither are the parts about stimulation of women's breasts being sexually arousing. If you want to ask about arousal experienced by men from nipple stimulation, then that's a separate question, not related to your title. Keep SE questions focused on one question and one question only.
If yes, why don't we hear/see/listen much about it
This is a purely opinion-based question that has nothing to do with biology, or really psychology for that matter. Leave it out.
If no, why (I assume you would say it's all mostly culture based)?
This also cannot be answered in any scientific way. One can speculate, but it's hard enough to scientifically answer "why" questions for things that exist, let alone those that do not. Leave this out.
Lastly, you've been, from my perspective, quite pushy and rude. You've asked this question 4 times on 3 different sites within just a few hours, and hardly responded to any feedback you've gotten except to complain it's not valid. Listen to feedback you get and try to understand it. Be patient: you were complaining on Skeptics.SE about not getting an answer on Biology Meta helping you with your question not even 2 hours after you posted here. Users here are not at your call, they're volunteering their time and expertise.
There is also a tendency for people to come to some of these sites and ask sexual questions for their own personal titillation. They're not looking for an answer to the question they claim to be asking, they actually just want to talk about sexuality with people on the internet. If you want to ask a science question about sexuality, keep to the science, otherwise it appears you have other motives.
