As someone who has not always been heavy I can say that when I was thinner I had many men approach me, i'd get hit on and flirted with. At my higher weight it's like I don't exist. So many men will not even look me in the eyes. I am married, but upon first sight many men wouldn't know that. So I have to say that if we are talking strictly quantity, being thinner had an impact on attention.
