Dating Ideas - Just for Fun!
Visit an Aquarium
Visit a local aquarium for a fun afternoon. Often times they have exhibits where you can feed the fish, or touch the sting rays.
Shopping
Go to your local shopping centre, or department store. Split up and spend £20 each on various products to use that night for a romantic and seductive evening together. Keep your purchases a surprise until later that evening.
Go for a Moonlit Walk
Take a walk, hand in hand, lit only by the moonlight.
