On the cooling DH jewels.... one thing my hubby does as soon as he comes home from work (4pm) is change from underwear and jeans to a pair of cotton shorts also called his sleeping shorts because that is what he wears to bed... when my boys were conceived it was either in the late evening (9-10pm) or first thing in the morning (6-8), we only used a lite cotton bed sheet in bed because the summer are fairly warm and also hubby likes a fan blowing on him all night.
