Thank you for your texts, guys.
It's really inspiring seeing people assuming their way, and it helps me trusting my way of being.
As said before, the only way is to assume, even if it means being "against" the other opinions.
You guys are lucky to be in the US, where I live in France, there are very few big girls, and it's part of the culture in a way to be against fat people...
I was shy about my taste in women, when I was younger (25 now). My parents met my ex-girlfriend by accident (they were aware that I like very big girls, because my dad found my history when I was 13, this was a big trauma, I was terribly ashamed during many years). But they met her and acted normally and they said nothing to me after this. I guess they understood my taste and that it cannot be changed.
Another episode, I was very close to a girl and we had a group of friends (not close friends, be people we knew and who where friendly). In the evening one of these friend came to me and said "look I don't know what you're doing with that girl but you shouldn't be with her, there are much better girls, why are you with her, she's fat" and so on. I was more disappointed than pissed, at that moment I understood my taste will "cost" me some relations. I decided to stand firm and told the guy it's my choice, I don't have to justify anything and that he should mind his business instead of being impolite. Of course the guy and I had less contact after that, but I was shocked as I considered him z friend before.
The truth his, your close circle will make the most comments and annoying questions. The people in the street don't care. Or maybe in a thin people country like mine, they'll raise eyebrows and laugh discreetly but that's all.
I got jokes from my real friend, but he totally understand.
You just have to put a respect boundary and not letting anyone crossing it.
In the end, just be a man and assume. As said previously, it's hard enough for the girls, and they definitely don't want to be with a guy who doesn't assume.
