Quoting *H3aTh3R*:" Yes when he doesnt remember, and the look in his eyes when it happens looks like he is out of this world! ... [snip!] ... like he is out of this world! Creepy and I want to know why. I have never heard of this type of sex drive happening to a girl!"
In mine and my husbands situation, it's different. I'm the one who is in a "zombie-like" state having sex in the middle of the night. I don't remember anything about it the next morning, and he's just sitting there all high and mighty explainin, in detail, what we did. I don't know why it happens, it used to only happen after I would take Benadryl right before bed, but the last couple times it's happened has been completely random!
