Imagine going to work tomorrow and getting an e-mail from someone you lust after inviting you to lunch. Imagine the offer feeling so compelling that you blow-off an appointment to meet this person for lunch.
Imagine meeting in a park and spreading a picnic on the ground. Imagine feeding each other, touching hands and face, kissing - while trying to avoid being too obscene as there are children playing nearby. Imagine telling that person something you enjoy about how they make you feel. Imagine lying on the ground next to them as they ask you to rate different "activities" they imagine for the two of you. Imagine fantasies you rarely speak of rolling off the tongue of your companion.
Imagine it's warm and the day feels lazy...and your apartment is just 5 minutes away with a comfy bed.
Imagine having to go back to work without ever going to your apartment, without anything more than a kiss with some tongue.
Would you get anything done for the rest of the day? I didn't.
