When people say crap like this, it usually means they're virgins and are jealous of others. I don't know why you would be jealous. It's not like sex is the most amazing thing on the planet, especially once the kids show up. --- Zero Stones! Zero Crates!
So its akin to being in the mood, either having a girlfriend or seeking someone to get into bed. Going through the act however innocent or as dirty as possible then afterwards not wanting to be touched or spoken to by the person you just had sex with?
