People who slag small penis?

My lovely best friend is so low and wants to kill himself because his ex girlfriend made fun of his manhood. All her friends thought he should be made fun of for this. His parents both died when he was young and I thought it was so courageous of him to let himself go with this issue. Why do sick people find this funny. If a woman had a mistectomy and was slagged for having small boobs it would destroy her and be so unacceptable or if a man had redefined cancer or was born with inter sex it would hurt them so much. Why is it socially acceptable to do this to men it causes them so much pain. I hate u people out there that do this and hope one day u understand that pain. These bitches have made me angry with the world!
