I agree, there is a body type that dominates porn and a body type that dominates high fashion and that neither sister is appropriate for high fashion.But I disagree to say someone looks good in porn is a compliment, but regardless of whether it is interpreted as a compliment or not, I do not think it is appropriate to say to anyone. Just because someones appearance fits a stereotype doesn't mean anything.
I don't take back what I said, but I recognise that I do approach this in the context that my ex-boyfriend would say this to me as if it were a compliment/teasing, but it made me feel degraded and I think for him, seeing me this way justified some of his treatment of me. It was just a really bad relationship and an awful experience for me, but it has also hardened me which will probably be a good thing. Hope this didn't turn into an overshare!
