See, you should be thanking me!
Well guys, count your blessings you haven’t got tiny spines on your penises. Scientists believe the key to evolution is man’s ability NOT to grow spines ,unlike our buddies the chimpanzees. These little lumps on the chimp’s junk are made of keratin, the same stuff as your fingernails and have kept them swinging in trees. Hmm and women, count your lucky stars men don’t have them, those friggin spines hurt. They are designed to damage the female chimp’s vagina so she doesn’t go off and mate with another male immediately after sex.
Ouch. Add another reason why it it good to be male
Oh not the spines?
