Won't go down..

Melissa
As you ladies are surely familiar with, in between waxes for the nether regions, you grow your hair out a bit for the best wax possible. 
Last night I was getting funky with my SO and he, unusually, refused to go down on me. After asking why, he said the hair made him feel uncomfortable/ doesn't find it appealing, even though he doesn't even trim for me and mine is merly millimetres short. He then refused sex altogether. 
Is it bitchy for me to be a little frustrated? It just seems to me that it's such an immature stance on his part. Am I wrong? 
UPDATE; according to his best mate, he is going to break up with me today. What a Keeper.
