Am I too harsh??

I was just watching 50 shades of Grey and joking with my friends in a whatsapp group about it and I said "well, I don't know where is the big deal: a hot guy gives you good sex, buy you expensive things and he doesn't stay for you to make him breakfast! It sounds like something I would have happily done in my 20s!" Then is this girl who calls me a sexist! Then I said "Well, you are the one who can afford to quit a job just because you didn't like it because your bf is a director and supports you" and she left the group all offended. Well, my hubby also makes 4 times the money I make and thanks of him we can afford nice things, so where is the problem?? I didn't say anything that wasn't true!
