sexualization of breasts

xxx
What do you think of sexualizing breasts. From what I've seen most of you believe they shouldn't be but then you also support porn. Which is ridiculously contradictory. 
You can't say "breasts aren't sexual" and "porn is good and acceptable" at the same time and think it makes sense. You sexualizing breasts yourselves then complaining when men etc. do it gives feminism a bad name. 
EDIT: I didn't mean to imply breastfeeding is sexual sorry I didn't clarify. It's totally fine in public and I agree it's not sexy or sexual. Sorry if that was midinterpretted.
