Rand question about anal play!

So ladies, i was reading a post on "men getting anal play by their significant other". NOW i believe about 50% of women said it was gross and would never do it! 30% women said they have done it and continue to do it ! 20% said they have never tried it but would ! Now out of the 50% of women that said they never done it and never would....about half said they would allow their men to give them anal play. This includes rim and whatever else. So why is it that , men getting it is so weird but for a women, it is okay?? Is it just the suspect gay scenario that always plays in the partner head when they realized their guy like it? Because let be honest ladies, i know plent of straight women that watch lady porn and like it. Noone instantly suspects them of being gay or at least not usually?? I feel like this is just another double standard.
