I have come out of lurking, I couldn't resist this one.
I myself do not like my breasts being touched unless I am in the mood. Moreso since I had children. I have an automatic reaction of pushing his hands away if I'm not in the mood. He needs my 'permission' to touch them. Feeling constantly under pressure to have sex only makes it worse. You feel like you need to fight for your right to control your own body.
I don't understand how you can think that touching someone's breasts is not sexual. If your wife touched your dick you say you would think you'd died and gone to heaven. Would you class that as a non-sexual act? Methinks you'd be hoping for a good old roll in the hay.
It can't come quickly enough
And now you've spent your life
Waiting for this moment
And when you finally saw it come
It passed you by and left you so defeated.
