Gets all cleaned up: Of course, he would want to smell attractive when he comes close to his woman. So if you see him cleaning up his act and taking special care of how he smells that particular evening, you should know there is something exciting coming up.
Gets touchy and personal: The build up starts early. So if he brushes past you, gently touches your face or simply gets touchy and physical, it means he is preparing the ground. And the touch can really be stimulating, both for men and women. So if he asks for a head massage or any other form of help that requires physical contact, that is a perfect hint.
Helps you out: Some days he will be extra nice and will switch on your favorite channel instead of insisting on watching a game or will help you in your daily chores. Being extra nice means there is something building up. Be ready.
