the only issur concerning men and women is talking or laughing which can lead to touching. singing is the same thing the only reason why a man cant listen to a women sing is because he will want her and will lead to bad things.
there is no problem blogging with a ‘women’ in reality is could be an old granny or a little boy !! you willl never know!!!!
dont you people work and email or call women in your company or other ones isnt that the same thing
