No.  Call me sexist or whatever, but Imma need for female personal trainers to be sexy.
Tell me, do you really think like this about women or you have heard this from someone else?
I think of it as common sense. They're only good for one thing, they should be sexy tho.
I think deep in your heart you know that women are more than sex objects and more than what you're saying about needing to be sexy. I would like to think that you are just uninformed, but saying things like that makes you really feel like a misogynist and I am not saying that you are but you are giving that vibe. I would say sorry to the people you have said things like this in the past and probably join a feminist group on Facebook so that you would know the best way to treat a woman.
